To check the principle of multiple proportions, a series of pure binary compounds (PmQn) were analyzed and their composition is tabulated below. The correct option(s) is (are)
| Compound | Weight % of P | Weight % of Q |
| 1 | 50 | 50 |
| 2 | 44.4 | 55.6 |
| 3 | 40 | 60 |
- If empirical formula of compound 3 is P3Q4, then the empirical formula of compound 2 is P3Q5.
- If empirical formula of compound 3 is P3Q2 and atomic weight of element P is 20, then the atomic weight of Q is 45 .
- If empirical formula of compound 2 is PQ, then the empirical formula of the compound 1 is P5Q4.
- If atomic weight of P and Q are 70 and 35, respectively, then the empirical formula of compound 1 is P2Q.
Answer
(D) If atomic weight of P and Q are 70 and 35, respectively, then the empirical formula of compound 1 is P 2 Q .
