Question

1 gram of N2 and 1 gram of O2 contains same number of nucleons​

Answer 1

Hello Dear,

● Answer with Explanation -

Moles of N2 are calculated by -

n(N2) = 1/14 mol

Molecules of N2 in 1 g are -

Molecules(N2) = 6.022×10^23 × n(N2)

Molecules(N2) = 6.022×10^23 × 1/14

Each molecule of N2 will contain 2×14 nucleons.

Total nucleons in 1 g N2 are -

Nucleons(N2) = 6.022×10^23 × 1/14 × 2×14

Nucleons(N2) = 12.044×10^23 nucleons ...(1)

Moles of O2 are calculated by -

n(O2) = 1/16 mol

Molecules of O2 in 1 g are -

Molecules(O2) = 6.022×10^23 × n(O2)

Molecules(N2) = 6.022×10^23 × 1/16

Each molecule of O2 will contain 2×16 nucleons.

Total nucleons in 1 g O2 are -

Nucleons(O2) = 6.022×10^23 × 1/16 × 2×16

Nucleons(O2) = 12.044×10^23 nucleons ...(2)

From (1) & (2), 1 gram of N2 and 1 gram of O2 contains same number of nucleons.

Hope this helps you...
