Question 5: (a) What do you mean by percentage composition of a compound? How the percentage of an element is calculated in a compound?
(b) Calculate the percentage composition of each of the following compounds. (Given atomic weights of the elements).
(i) MgSO4 (ii) C3H6O (iii) KMnO4 (iv) C6H6 (v) NaAl(SO4)2 (vi) CaCO3 (vii) CH4
[Mg = 24, S = 32, O = 16, C = 12, K = 39, Na = 23, Mn = 55, Ca = 40, Al = 27, H = 1]
