There are 2.45 moles of gas at a pressure of 38.4 atm and a temperature of 401 K. What id the volume

Answer 1

Use the ideal gas law PV = nRT where P is pressure in "atm" (atmospheres), V is volume in liters, "n" is moles, "R" is the ideal gas constant which you must look up but is 0.0821 (atm•L)/(mol•K), and "T" is temperature in Kelvin

PV = nRT

V = (nRT)/P

V = (2.45)(0.0821)(401)/(38.4) = 2.10 liters
