Okay, in this problem, we're asked to solve for the concentration of sucrose, which is this sugar compound in 355 milliliters of iced tea.
00:13
Now, recall that concentration is molarity in chemistry.
00:18
So we need to solve for molarity.
00:21
And molarity is equal to the moles of the solute over the liters of solution.
00:25
Now, as a quick review, the solute is what gets dissolved.
00:31
In this case, that's going to be the sugar.
00:34
I'm going to highlight that in purple to keep track of it.
00:38
And then the second part is going to be the stuff that does the dissolving, or the overall solution, is going to be the iced tea.
00:49
And so in order to solve for this, we need the moles of our sugar and liters of our iced tea.
00:58
In order to get the moles of the sugar, we're going to do a mole conversion step.
01:03
So we have 43 grams of the sucrose, grams of sucrose on the bottom, that way that those two things will cancel.
01:21
And the moles is what we're looking for that goes on top.
01:28
And one mole is equal to 342 .3 grams of the sucrose...
