What will be the number of moles of a gas with a pressure of 4.44atm at a temperature of 149˚C in a container with a volume of 5.00 Liters?

Answer:

0.641 moles

Explanation:

Apply the ideal gas law: PV = nRT

Since we're looking for number of moles, solve for n:

n = PV / RT

Plug in our values given: 4.44 atm, 5.00 L, 0.08206 (ideal gas law constant for atms), and 422.15 K (149˚C in K for our ideal gas law equation):

n = (4.44 * 5.00) / (0.08206 * 422.15) = 0.641 moles (3 significant figures)
