how much cuso4.5h2o would you need to weigh out if you wanted a sample that contains 5.00 mol of H atom
Nadusha1986 [10]

1 mole of CuSO4.5H2O = 249.68 g/mol


1 mole CuSO4.5H2O contains 10 moles of H


Therefore 0.5 moles of CuSO4.5H2O contains 5 moles of H


Moles x Mr = Mass

0.5 x 249.68 = 124.84g
