Question

Calculate the number of mol of helium in a 2.01-L balloon at 29°C and 2.71 atm of pressure. Be sure to answer all parts. Imol

Answer 1

Answer:

0.220 mol He

Explanation:

Hello,

Based on the ideal gas equation of state:

$PV=nRT\\n=\frac{PV}{RT} \\n=\frac{2.71 atm * 2.01 L}{0.082\frac{atm*L}{mol*K}*302K } \\n=0.220 mol$

Best regards.
