And this problem, we're informed that we start with 2 .04 grams of vanadium and combine it with 1 .93 grams of sulfur to produce a compound.
00:09
And we're trying to figure out what the empirical formula of the product is.
00:14
So what we're going to do here is we need to figure out the moles, how many moles of each of these substances there is available.
00:21
And then use that to find a molar ratio, which will give us our subscripts x and y.
00:26
So first off, we're going to take the 2 .04 grams of vanadium and divide it by its molar mass, which is 50 .94 grams, and we get that that is 0 .04 -00 moles of vanadium.
00:45
We'll do the same thing with sulfur, 1 .93 grams of sulfur, divided by sulfur's molar mass, which is 32 .07 grams...
