AIIMS 2019 Chemistry Empirical Formula MCQ Question
The atomic mass of M is 34 and its abundance is 68% and remaining is 32% oxygen. The atomic mass of oxygen is 16. The empirical formula is calculated below. So, the empirical formula is M₂O₂ or MO.

Correct Answer
Detailed Explanation
To determine the empirical formula, we first calculate the moles of M and O based on their atomic masses and abundances. With M having an atomic mass of 34 g/mol and an abundance of 68%, and O having an atomic mass of 16 g/mol and an abundance of 32%, we find the ratio of moles of M to O is 1:1, leading to the empirical formula of MO. Other options are not relevant as they do not provide valid empirical formulas based on the given data.
