This is a Multiple Choice Questions as classified in NCERT Exemplar

Option(C), (D)

The number of moles is given by the following formula,

Moles = $\frac{M a s s}{M o l a r m a s s}$ ---------------(1)

The number of molecules can be calculated as, number of moles

= $\frac{n u m b e r o f m o l e c u l e s}{A v o g a d r o s n u m b e r}$ ----------(2)

(C) The number of moles of N₂ is calculated by using equation (1) as follows,

Moles of N₂ = $\frac{14 g}{28 g / m o l}$ = 0.5 mol

The number of molecules can be calculated by using equation (2) as follows,

0.5 mol = $\frac{n u m b e r o f m o l e c u l e s}{6.022 * 10^{23}}$

number of molecules = 0.5 $*$ 6.022 $*$ 10²³

(D) The number of moles of H₂ is calculated by using equation (1) as follows,

Moles of H₂ = $\frac{1 g}{2 g / m o l}$ = 0.5 mol

The number of molecules can be calculat
