How many moles of a gas does it take to occupy 230 liters at a pressure

of 1.5 atmospheres and a temperature of 270 K? Use. 0821 L-atm/k-mol.

Answer: n=15.56moles

Explanation:

PV = nRT

where

P is pressure in atmospheres

V is volume in Liters

n is the number of moles of the gas

R is the ideal gas constant = given as (0.0821L - atm/k-mol

PV = nRT

n = PV/RT

n = (1.5 X 230) / (0.0821 X 270)

n = 15.56 moles
