in a empirical formula lab how do you calculate the number of moles of Cu in 0.0114 moles of CuSo4*H2O? Thanks
There is 1 atom Cu in 1 molecule of CuSO4.H2O; therefore, 0.114 mol CuSO4.H2O must contain 0.114 mols Cu.
It also contains 0.114 mols S, 5*0.114 mols O [that's 4*0.114 from CuSO4 and another 0.114 from the O of H2O] and 0.114 mols H2O (and that can be broken down to 2*0.114 mols H and 0.114 mols O from the H2O alone).
