Question

Compute gram molecular weight of H2 gas if 4 g of H2 gas contains 24.09 × 1023 atoms

Answer 1

Please mark me brainliest and follow me

There are 24.09 × 10²³ atoms in 4g of hydrogen

So, mass of one hydrogen atom will be:

$\frac{4}{24.09x10^2^3}$ ≅ 0.166 x 10⁻²³ g = 1.66 x 10⁻²⁴ g

Since there are 2 atoms in H₂ the mass will be:

2 x 1.66 x 10⁻²⁴ g = 3.32 x 10⁻²⁴ g
