Question

the volume of 2g of O2 at N.T.P is

Answer 1

The volume of 2g of $O_{2}$ at Normal Temperature and Pressure (N.T.P) is 1.4 litre.

To determine the volume of 2g of $O_{2}$ at Normal Temperature and Pressure (N.T.P) we need the following information:

Moles of Oxygen $\left(\mathrm{O}_{2}\right)$ = Given mass of Oxygen / Molecular mass of Oxygen  

$=\frac{2}{32}=\frac{1}{16}$

Total volume of 2gm of Oxygen at Normal Temperature and Pressure (NTP)  

$\begin{array}{l}{=\text { number of moles } \times \text { volume of each mole }} \\ {=\frac{1}{16} \times 22.4\ \text {litre}} \\ {=1.4 \text { litre. }}\end{array}$
