The new volume of the hydrogen gas at s.t.p., [tex]V_{2}[/tex] = 750 dm³
What is the molar volume of gas at s.t.p?
The molar volume of a gas at s.t.p. is 22.4 dm³.
The change in volume gases at different temperatures and pressures are given by the general gas equation given below:
- [tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]
[tex]V_{1}[/tex] = 600 dm³
[tex]P_{1}[/tex] = 950mmHg
[tex]T_{1}[/tex]= 273 K
The new volume of the hydrogen gas at s.t.p., [tex]V_{2}[/tex] is calculated thus:
[tex]V_{2}[/tex] = (950 x 600 x 273)/(760 x 273) = 750 dm³
In conclusion, the volume of a gas changes with temperature and pressure changes.
