To check the principle of multiple proportions, a series of pure binary compounds (PQ) were analyzed and their composition is tabulated below. The correct option(s) is(are) Compound 1 2 3 Weight % of P 50 44.4 40 Weight % of Q 50 D 55.6 60 (A) If empirical formula of compound 3 is P3 Q4, then the empirical formula of compound 2 is P3 Q5. (B) If empirical formula of compound 3 is P3Q₂, 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 compound 1 is P, Q4. (D) If atomic weight of P and Q are 70 and 35, respectively, then the empirical formula of compound 1 is P₂Q.
