Calculate the volume occupied by 1.76 mol of gas at a pressure of 2.85 atm and a temperature of 355k

18.0L is the volume occupied by the gas under these conditions

Explanation:

Using combined ideal gas law it is possible to find the volume of a gas with moles, pressure and temperature of this one, thus:

PV = nRT

V = nRT / P

Where P is pressure (2.85atm), V is volume in liters, n are moles of gas (1.76mol), R is gas constant (0.082atmL/molK) and T is absolute temperature (355K)

Replacing:

V = 1.76mol*0.082atmL/molK*355K / 2.85atm

V = 18.0L

18.0L is the volume occupied by the gas under these conditions
