I must have the same sheet as you as I have the exact same question.
Okay,
The RFM of Manganese (Mn) is 54.9
The RFM of MnSO4 4H20 is 223
The percentage of Mn in MnSO4 4H2O is 54.9/223 X 100 and that is 24.6 %
0.1 Moles of MnSO4 4H20 is 223/100 X10 = 22.3
24.6 % (percentage of Mn in MnSO4 4H2O) of 22.3 (0.1 Moles of MnSO4 4H2O) is 5.49g
Then you do 5.49g/54.9g (RFM of Mn) which is 0.1 Moles of Mn, which is your answer.
