Two elements 'P' and 'Q' combine to form a compound. Atomic mass of 'P' is 12 and 'Q' is 16. Percentage of 'P' in the compound is 27.3. What will be the empirical formula of the compound?

A$$P_2Q_2$$
BPQ
C$$P_2Q$$
D$$PQ_2$$
Correct Answer

Solution

Element mass% Atomic mass(g) $$\dfrac{mass\%}{At. mass}$$ Integral ratio
P 27.3 12 2.275 1
Q 72.7 16 4.5 2
Empirical formula is $$PQ_2$$
