NEET Chemistry Percentage Composition MCQ Question
Calculate the percentage composition of copper in copper sulfate (CuSO4). (Atomic masses: Cu = 63.5, S = 32.1, O = 16.0)
39.81%
31.83%
45.11%
25.47%
Correct Answer
Detailed Explanation
To find the percentage composition of copper in CuSO4, calculate the molar mass of CuSO4 (63.5 + 32.1 + 4 * 16.0 = 159.6 g/mol) and then determine the percentage of copper: (63.5 / 159.6) * 100 ≈ 39.81%.
