Given:

Number of moles, n = 1 mol

Temperature, T = 0°C

Pressure, P = 1 atm

Let's find the volume.

To find the volume apply the ideal gas law:


PV=nRT

Where:

• P is the pressure = 1 atm

,

• T is the temperature in kelvin = 0°C + 273 = 273 K

,

• n is the number of moles = 1 mol

,

• R is the universal gas constant = 0.08206 L.atm/mol.K

,

• V is the Volume.

Rewrite the formula for V:


V=(nRT)/(P)

Substitute the values into the formula and solve for V:


\begin{gathered} V=(1*0.08206*273)/(1) \\ \\ V=22.4\text{ L} \end{gathered}

Therefore, the volume is 22.4 L

ANSWER:

22.4 L
