Question

If the pressure is 100,000 Pa, R is 8.314, the temperature is 300 K, and the number of moles of gas (n) is 100, what is the volume in m3?

Answer 1

We can solve the problem by using the ideal gas equation:

`pV=nRT`
where
p is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature of the gas

For the gas in our problem, we have:

`p=100000 Pa`

`R=8.314 J mol^(-1) K^(-1)`

`T=300 K`

`n=100`

If we rearrange the equation and we put these numbers into it, we find the volume of the gas:

`V= (nRT)/(p)= ((100)(8.314)(300))/(100000)=2.49 m^3`
