NEET Chemistry Atomic & Molecular Mass MCQ Question
If the molecular mass of a compound is found to be 46.068 u and it contains 34.73% oxygen by mass, what is the mass of oxygen in one mole of the compound?
16.00 g
18.02 g
15.98 g
17.00 g
Correct Answer
Detailed Explanation
Using the mass percentage of oxygen (34.73%) and the molecular mass of the compound (46.068 u), the mass of oxygen in one mole of the compound is calculated as (34.73/100) * 46.068 = 16.00 g.
