How do you solve for V2, using Avogadro's Law when moles of a gas are added(n2)? A sample containing 7.20g O2 gas has a volume of 35.0L. Pressure and temperature remain constant. What is the new volume if 0.800mole O2 gas is added?

In your problem,
So we have
If we add
This makes sense.
The number of moles increased by about fivefold, so the volume should have increased about five-fold (to about 175 L).
