# What is the volume of gas inside this balloon?

## A balloon is floating around outside your window. The temperature outside is 39°C, and the air pressure is 0.700 atm. Your neighbor, who released the balloon, tells you that he filled it with 3.30 moles of gas

$V = \frac{n R T}{P} \cong 120 \cdot L$
V=(3.30*molxx0.0821*L*atm*K^-1*mol^-1xx312*K)/(0.700*atm)=??L
