If I have 12 moles of gas with a temperature of 16°C, what is the volume of the gas if the pressure is 14atm

20.3 L

Explanation:

Assuming that the gas behaves similar to an ideal gas we can use the ideal gas law equation

PV = nRT

Where

P - pressure - 14 atm

V - volume

n - number of moles - 12 mol

R - universal gas constant - 0.0821 L. atm / mol. K

T - absolute temperature - 16 degrees + 273 = 289 K

Substituting the values in the equation

14 atm x V = 12 mol x 0.0821 L. atm/mol. K x 289 K

V = 20.3 L
