Question

find the number of hydrogen and carbon atoms in 15.6 gm of C6H6​

Answer 1

Explanation:

Molar mass of C6H6 is 78g

Therefore number of molecules in 15.6g = 78/15.6 = 6 mol

Each molecule has 6 C atoms and 6 H atoms

Therefore no. of C atoms is 6 mol = 6 × 6.022 × 10^23 = 36.132 × 10^23

Therefore no. of H atoms is 6 mol = 6 × 6.022 × 10^23 = 36.132 × 10^23
