Introduction to Limiting Reactant and Excess Reactant
 
16:58
Limiting reactant is also called limiting reagent. The limiting reactant or limiting reagent is the first reactant to get used up in a chemical reaction. Once the limiting reactant or limiting reagent gets used up, the reaction has to stop and cannot continue. After the limiting reactant or limiting reagent is used up and the reaction stops, there is extra of the other reactants left over. Those are called the excess reactants. In this video, we'll first learn about limiting reactant and limiting reagent by comparing chemical reactions to cooking recipes. We'll look at how to calculate limiting reactant and limiting reagent using cooking ingredients, and then looking at an actual stoichiometry problem,

We'll learn how to convert back and forth between grams and moles. For each example, we'll do it two ways. First, a thinking through it approach, that shows how you multiply moles by the molar mass to convert from moles to grams, and how you divide grams by the molar mass to convert from grams to moles. Second, we'll use a conversion factor method where we write units based on molar mass information, and set up fractions to correctly cancel the units.

How to Calculate Molar Mass (Molecular Weight)
 
03:51
Finding molar mass (also called molecular weight, molecular mass, and gram formula mass) is an essential skill in chemistry, especially for mole to gram conversions. There are three steps to finding the molar mass for a compound: Steps 1 – Find the atomic mass of each element. Step 2 – Multiple the atomic mass of each element by its subscript. No subscript means it is “1”. Step 3 – Add up all masses and add units (grams/mole or g/mol). --- Supporting videos (complete explanations): HCl: https://youtu.be/tDVYav28GaA O2: https://youtu.be/W2ePrieqiDU Ca(NO3)2: https://youtu.be/W89M6c9Tu68 Al2(SO4)3: https://youtu.be/m75CUhLXCIU MgSO4 - 7H2O: https://youtu.be/6b6GadB28o4 --- A few things to consider when finding the molar mass for: - make sure you have the correct chemical formula. - always include the units for molecular weight (grams/mole). - make sure you do the math right - follow the order of operations.

How To Find The Amount of Excess Reactant That Is Left Over - Chemistry
 
13:43
This chemistry video tutorial explains how to find the amount of excess reactant that is left over after the reaction is complete. You need to start with the limiting reactant and convert that quantity into the grams of excess reactant. This represents the amount of excess reactant that is actually consumed or used up in the reaction. The difference between the starting amount of excess reactant and the amount that is consumed is equal to the amount of excess reactant left over. This chemistry tutorial contains plenty of examples and stoichiometry practice problems.

Reacting Mass Calculation: Water of Crystallisation.
 
03:26
This short flash animation shows how we can determine the number of moles of water of crystallisation in a hydrated salt such as washing soda. The salt is weighed, then heated, cooled and reweighed over and over until a constant mass is reached. The ratio of anhydrous salt to water of crystallisation is determined in grams and converted to moles.

Stoichiometry Problem: Mass Precipitate
 
05:21
Erika Tan walks through a sample mass precipitate problem for all levels of chemistry. TRANSCRIPT: So here we have a stoichiometry problem saying that a 45 milliliter sample of .3 molar FeCl3 is reacted with enough NaOH solution to precipitate all the iron as Fe(OH)3. How many grams of Fe(OH)3 will be precipitated? So the very first thing that you want to do in this type of situation is to balance the equation. Here we have FeCl3 reacting with NaOH and that yields a product of Fe(OH)3 and there’s one more product, since the Fe and OH ions are making Fe(OH)3, we’re left with Na and Cl, and that’s going to be another product. And since the charges of both of them are one, sodium is +1 and chloride is -1, both of them have subscripts of one when they combine. Now all we have to do is balance the coefficients. I see we have 3 chlorides here, so that means we need to add a 3 in front of the sodium chloride, and then we also have 3 hydroxides on this side, meaning we should add a 3 here. So now we have 1 iron ion, 3 chloride ions, 3 sodium ions, and 3 hydroxide ions. Now what we want to do is use this formula, M x V = moles, because it gives us the molarity of FeCl3 and the volume of it. So molarity times volume = moles. So I’m just going to write that down here, .300 molarity, which is moles over liters, times how many liters we have of the FeCl3 which is 45 milliliters. And if you change that to liters you get .045 liters. And now we have .3 times .045 and that gives us .0135 moles of FeCl3. So now, I’m going to use the amount of moles of FeCl3 that I have, and use the balanced equation to see how many grams of Fe(OH)3 will be precipitated. So this is how many moles of FeCl3 that I have, .0135 FeCl3, and the mole ratio for FeCl3 to Fe(OH)3 is 1 mole of FeCl3 for every 1 mole of Fe(OH)3. So now, we need to use the molar mass of Fe(OH)3 to find the amount of grams. So let’s look at the periodic table here, and it has a molar mass of 55.8. And then OH is 17 grams, and we have 3 hydroxide ions, so 17 times 3 plus the molar mass of iron which is about 56 grams gives us 107 grams. 107 grams of Fe(OH)3 per mole. Now we can cross out the moles of FeCl3, and the moles of Fe(OH)3 cancel out, giving us only grams of Fe(OH)3. Now let’s plug these numbers into the calculator, .0135 times 107, and that gives us about 1.4445 grams of Fe(OH). So that’s your final answer. 1.4445 grams of Fe(OH)3. And if you want to keep in the practice of using the correct amount of sig figs, I would use 3 sig figs because this number has 3 significant figures, so if we’re going to use 3, we would just cut off these two, and that leaves us with 1.44 grams of Fe(OH)3.
