All right, so let's take a look at part a first.
00:05
So in part a, we have 17 .3 grams of sucrose.
00:12
And we have a volume of 246 milliliters.
00:22
And what we need to find is the molarity of the solution.
00:26
So remember that molarity is equal to moles over liters.
00:32
We don't have liters yet, but we can convert miller.
00:35
Liters into liters.
00:37
Every one liter is a thousand milliliters.
00:41
So that's going to be 0 .246 liters.
00:47
So we have our denominator.
00:50
But we need the number of moles.
00:52
We don't have moles.
00:52
We have grams.
00:54
So what we're going to have to do is multiply by the molar mass.
00:58
And we're given the molar mass and the problem, it's 342 .3 grams per mole.
01:06
So that's 0 .5 .0 .5 .1...
