13) (a) & (c)-CH is the empirical formula.
(b) & (d)-CH₂O is the empirical formula.
14)Total mass of MgSO₄.7H₂O=246, mass of water=126
% of water = (126 x 100)/246 = 51.2%
All the other questions are somewhat similar to this, find the % of each with respect to total mass.
By the way, calcium's atomic weight is 40.
