Question

If the pressure exerted by a gas at 100 Celsius in a volume of 0.044 L is 3.81 atm, how many maples of gas are present

Answer 1

The number of moles of gas present are 0.0054

Explanation:

Given-

Temperature, T = 100°C = 100 + 273 = 373K

Volume, V = 0.044L

Pressure, P = 3.81 atm

Moles of gas, n = ?

We know,

PV = nRT

R = 0.082 L.atm.K⁻¹.mol⁻¹

n = PV/RT

n = (3.81)(0.044)/(0.082)(373)

n = 0.0054 moles

Therefore, number of moles of gas present are 0.0054
