 Okay, so let's try to calculate the number of moles in 15 grams of sodium salt. So the first thing you need to do is figure out the molecular weight of sodium salt. So in order to do that, we just did 0.0 grams this way, right? Because we want to cancel the grams out and get moles, right? So the grams are going to cancel there. And all we do now is take 15 and divide it by 141. 0.106. So that's what's the correct number of 6. You guys got that one.
