3.6 x 10^24
There's 2.016 g/mol of H2, so divide that into 12g. Then multiply by Avogadro's number

The particles are molecules in this case:
(12 g H2) / (2.01588 g H2/mol) × (6.022 × 10^23 molecules/mol) = 3.6 × 10^24 molecules H2
(12 g H2) / (2.01588 g H2/mol) × (6.022 × 10^23 molecules/mol) = 3.6 × 10^24 molecules H2
