Question
Potassium sulphate is isomorphous with potassium chromate which contains 26.79% by mass of chromium. The atomic mass of chromium is
Options
A.24
B.32
C.51.96
D.53.2
Solution
The chemical formula of potassium sulphate is $K_{2}SO_{4}$and hence, potassium chromate is$K_{2}CrO_{4}$.
Molecular mass = $2 \times 39 + A + 4 \times 16 = 142 + A$
From question, $(142 + A) \times \frac{26.79}{100} = A \Rightarrow A = 51.96$
