Question

Determine the volume occupied by 0.285 moles of a gas at 15°C if the pressure is 81.8 kPa?

Answer 1

`"8.35 L"`

Explanation:

Use ideal gas equation `PV = nRT`

`V = (nRT) / P`

`V = ("0.285 moles" × "0.0821 L atm /(mol K)" × (15 + 273)"K")/(81.8 cancel"kPa" × "1 atm"/(101.325 cancel"kPa"))`

`V = "8.35 L"`
