The weight of 1 × 1022 molecules of . 5 is — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The weight of 1 × 1022 molecules of $CuSO_4$. 5$H_2O$ is
Answer: C
💡 Solution & Explanation
4 2 .5 CuSO H O has molecular mass= 249.5 g/mol. 23 6.023 10 x molecule has molecular mass = 249.5 g/mol. Therefore, 22 1 10 x molecule has molecular mass= 22 23 249.5 10 / 6.023 10 x x = 4.1 g.
