Hi! so to solve for this, we will calculate the number of moles of the component elements.
00:06
We'll start with tin.
00:09
Tin, the symbol for tin is sn, and we have 0 .500 grams of tin.
00:16
Convert this to moles by dividing the molar mass of tin from the periodic table.
00:20
That's 118 .7 grams, and we have here moles.
00:24
So that means we could cancel grams here, and we'll get 4 .21 times 10 to the negative 3.
00:31
This is moles of sn, and we have oxygen since this is tin oxide.
00:39
So that means we'll subtract the mass, 0 .635, and then the mass of tin, that's 0 .500 grams.
00:46
Divide the molar mass of oxygen here, 16 grams.
00:50
We have here moles, and then we'll cancel grams, and we'll get 8 .4375 times 10 to the negative 3...
