Question

The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mass of lindane is 290.8 g/mol. How many atoms of carbon does a molecule of lindane contain?

Answer 1

Answer:

3.61x10²⁴ atoms of C are contained in a molecule of lindane

Explanation:

Formula for lindane is C₆H₆Cl₆.

This compound has 6 mole of carbon, 6 mole of hydrogen and 6 mole of chlorine

6.02x10²³ atoms . 6 mol = 3.61x10²⁴ atoms

1 mol has NA of atoms
