1. If empirical formula of compound 3 is P₃Q₄, then the empirical formula of compound 2 is P₃Q₅.
2. If empirical formula of compound 3 is P₃Q₂ and atomic weight of element P is 20, then the atomic weight of Q is 45 .
3. If empirical formula of compound 2 is PQ, then the empirical formula of the compound 1 is P₅Q₄
4. If atomic weight of P and Q are 70 and 35, respectively, then the empirical formula of compound 1 is P₂Q.

Answer

(B) If empirical formula of compound 3 is P 3 Q 2 and atomic weight of element P is 20, then the atomic weight of Q is 45 ., (C) If empirical formula of compound 2 is PQ, then the empirical formula of the compound 1 is P 5 Q 4
