Question

6.023×10^22 atoms of hydrogen can make ........moles of H2 Molecules​

Answer 1

Number of atoms in 1 mole = 6.022 × 10²⁴

Number of atoms in 1 H2 molecule = 2

So,

number of H2 molecules in 6.023 × 10²² atoms

==> 6.023 × 10²² ÷ 2

==> 3.0115 × 10²² molecules

Number of moles = Number of molecules ÷ Avogadro's number

==> 3.0115 × 10²² ÷ 6.022 × 10²⁴

==> 0.5000 × 10^-2

==> 0.005 moles
