What mass of magnesium sulfate will be produced by the reaction?
moles of Mg = mass / RAM = _______ / _______ = _______
is From the balanced equation the ratio of Mg to MgSO4 is 1:1
so the moles of MgSO4 = _______ .
RFM of magnesium sulfate = _______
mass of magnesium sulfate = moles x RFM
mass of magnesium sulfate = 0.125 x 120 = _______ g
