So in the problem, we are given a 50 -100 gram bleach solution, and we are told that 3 .62 % of the mass of the solution is composed of the solute sodium hypochlorite.
00:11
We are then asked to find the grams of the solvent in the solution.
00:16
So there's two ways we can answer this question.
00:18
So the first way is we can find the mass of the solute and subtract that from the total mass of the solution in order to find the mass of the solvent.
00:26
So let's do that.
00:27
So we need to first convert the percentage into its size.
00:31
Decimal form and then multiply that by 1500 to find the mass of the solute.
00:36
So 3 .62 divided by 100 to get it in its decimal form equals 0 .0362.
00:47
We can then take this times the total amount of solution, 1 ,500, to give us the mass of the solute.
00:57
And that will be 54 .3 grams of sodium hypochlorite.
01:04
Now this is the solute, so the rest of the solution will be the solvent.
01:10
So we can take 1500 and subtract 54 .3 from it to give us our mass of solvent in the solution.
01:20
So 1445 .7 grams of solvent...
