Hydrogen gas = H2
molecular mass = (1×2) = 2 g
No of moles in 10g of H2
= 10/2
= 5 moles
No. of molecules in 5 Moles of H2
= 5× 6.022×10^23
= 30.11 × 10^23 molecules
molecular mass = (1×2) = 2 g
No of moles in 10g of H2
= 10/2
= 5 moles
No. of molecules in 5 Moles of H2
= 5× 6.022×10^23
= 30.11 × 10^23 molecules

Gram molecular mass of hydrogen = 2g
2g = 1 mole
10 g = 10/2 = 5 moles
Number of molecules at STP =
5 x 6.023 x 10^23 molecules
= 3.011 x 10^23 molecules
2g = 1 mole
10 g = 10/2 = 5 moles
Number of molecules at STP =
5 x 6.023 x 10^23 molecules
= 3.011 x 10^23 molecules
