Okay so now I'm going to do a whole bunch of mole ratio problems a whole bunch so you can really get a handle on these they're super important for stoichiometry for understanding stoichiometry okay each problem I'm going to do it two ways first I'm going to treat the equation the chemical equation kind of like kind of like a recipe all right where we've got our ingredients and then we've got the step we're baking this method really makes sense like you'll understand what you're doing but it requires a little bit of thumb then I'll solve each probably using a conversion factor method the conversion factor method doesn't require any thought but it doesn't make any sense so it's really easy to get in the habit of only using the conversion factors running through the math but having absolutely no idea what you're actually doing or why you're doing it okay so that's why I'm going to do each of these problems two different ways okay so let's get started here is the first equation I'm going to be working with two moles of h2o water makes two moles of hydrgas and oxygen here if there's no coefficient in front of the oxygen in front of one of these chemicals we know that it's really one that it means one mole so hey if it helps you go ahead and write that one there's our equation here is the question how many moles of o2 of oxygen will be produced from six point two moles of water okay so first of all I want you to think of this like a recipe and right now it's saying that we start with two moles of this and that gives us two moles of this and one mole of...
