And there, in this question, we are trying to make a percent solution, and it's a percent weight per volume.
00:13
So what that means is we need the mass of the solute divided by the volume of the solution.
00:29
It's going to give us a decimal number, so then we would multiply by 100 and add that percent sign.
00:35
Okay, so this is what our equation is going to look like.
00:37
We are given the percent.
00:38
We are told that it is 5 percent.
00:46
Mass of the solute is what i'm trying to determine, because that is what is not given here.
00:55
We are given the total volume.
00:57
It is 200 milliliters.
01:04
All right.
01:04
The first thing i want to do is divide both sides by 100 % to get those percents out of here.
01:09
So if i divide the left by 100%, i get 0 .05...
