To calculate the concentration of copper 2 sulfate, i'm going to assume that you measured an exact mass of 18 grams, copper 2 sulfate.
00:12
If you didn't, then just make sure that you put in the actual mass that you measured in this calculation.
00:20
Concentration, copper 2 sulfate, is always moles, copper 2 sulfate, divided by the liters of the solution.
00:29
So if you measured out 18 grams, copper 2 sulfate, to get moles copper 2 sulfate in the numerator, we need to divide by the molar mass.
00:41
So we can calculator, look up the molar mass of copper 2 sulfate.
00:46
There are 159 .61 grams copper 2 sulfate in one mole.
00:54
Now that we have moles copper 2 sulfate, we'll simply divide by the volume...
