The pressure inside the cylinder is $8.327\times 10^{-3}$ atmospheres.

The value for R for this problem is 0.082 atmosphere-liters per mol-Kelvin.

Explanation:

Let suppose that helium gas inside the cylinder behaves as an ideal gas, the equation of state for the ideal gas is:

$P\cdot V = n\cdot R_{u}\cdot T$ (1)

Where:

- Pressure, measured in atmospheres.

- Volume, measured in liters.

- Molar quantity, measured in moles.

- Temperature, measured in Kelvin.

$R_{u}$ - Ideal gas, measured in atmosphere-liters per mole-Kelvin.

If we know that $V = 60\,L$ , $n = 0.020\,mol$ , $T = 304.65\,K$ and $R_{u} = 0.082\,\frac{atm\cdot L}{mol\cdot K}$ , then the pressured inside the cylinder is:
