So in this question, first, we're going to find the masses of both of the compounds containing sulfur.
00:08
So we have the percentage of each compound that makes up the total mass.
00:12
So take the total mass and then multiply by the percentage of the compound that is going to be copper sulfide.
00:23
Then we need to convert to the mass of the sulfur dioxide.
00:29
When we want to do that, we need to first write the balanced chemical reaction.
00:34
And the products are going to be copper oxide or specifically it's cuprits.
00:43
So it has an oxygen state of plus one.
00:45
So cupris oxide and it's sulfur dioxide.
00:49
And then we're going to convert using dimension analysis to mass of the sulfur dioxide.
00:59
So then we find the mass of the iron sulfide.
01:05
So we do the same thing...
