 Anyways, how many grams are in 0.0626 moles of sodium bicarb, bicarbonate? The main ingredient in alpha salts are tablets. So it gives us the number of moles as 0.0626. So that's the number of moles of bicarb in a tablet. So we want to figure out how many grams is that going to be. So remember we just learned about the conversion between grams and moles, or moles and grams. Do you guys remember what it was called? The molar mass, right? Okay, so how do we figure out the molar mass? Well we know that in this case the formula unit, because it's an ionic compound, right? We know the formula unit. So we're going to figure out the molar mass using that formula unit. So the molar mass of sodium bicarb is going to be, well we look up, we have one sodium, right? 22. And remember molar mass, what's the units? Grams per mole. Plus one hydrogen. Plus one carbon. Plus three oxides. So it's two digits after the decimal. 84.01 grams per mole. So that's the molar mass of sodium bicarb. So we should be able to use that to convert this to grams. Does everybody agree with me yet? Yeah? Okay, good. So how do I do that? Remember that's a ratio. So we're trying to get rid of moles, and we're trying to get grams so we just multiply the two by each other. Just to formally show the ratio, like we like to do in Jim Kim, right? You want to put the moles on the bottom, the grams on the top, like that. So when we do that, of course, that cancels out moles like that. One, two, three signals that I got. It seems like a huge alphabet.
