Question

Calculate the molecular mass of the following compounds:-

Answer 1

Answer:

a) 180 u, b) 60 u c) 249.5 u d) 286 u e) 98 u f) 100 u

Explanation:

All you need to calculate molecular masses of compound is to know the atomic masses of elements they contain. Molecular mass is the sum of atomic masses of all the elements present in a compound. Here is the way of calculating molecular mass. Let's take the example of Calcium carbonate( CaCO3 ) . The atomic masses of Ca, C and O are 40 , 12 and 16 respectively. Now 40 + 12 + 16 ×3 = 40 + 12 + 48 = 100 u.
