Question

a gas mixture contains 20% of H2 AND 80% OF O2 . FIND THE TOTAL NO. OF MOLECULE IN 1gm of the gas mixture​

Answer 1

Answer:

Molar mass of h2 molecule is 2 (atomic mass 1*2 atoms= 2) and that of O2 is 32Thus by gram molecular mass theory, 2g H2 will have 1 mole h2 molecules and therefore 0.2g should have 0.1mole = 6.02*10^22Similarly on solving for o2, we get 1.505*10^21 molecules.
