If 30g of CuSO4 • 5H20 are present, how many moles of CuSo4 • 5H2O are present?
I need help with this chemistry question please? Silly me didn't copy fast enough when my instructor was working on the problem on the board & was also focusing how he was solving it as well. I worked on the problem on my own, but I don't know if I got it right, so, I just want to make sure I got the right answer, or that I aleast was close to getting the correct answer. Thank-you! I truly appreacite anyone's help! :)

The molar mass of the compound must include the 5 waters of hydration. Dividing the mass by the correct molar mass will give you the number of moles.
(30 g CuSO4 • 5H2O) / (249.685 g CuSO4 • 5H2O/mol) = 0.12 mol CuSO4 • 5H2O
