To what temperature in K must a variable volume container of helium gas be cooled to obtain a final volume of 0.182 L? The initial volume and temperature are 2.34 L and 314 K, respectively. The pressure and number of moles are fixed.

You're supposed to us V1/T1=V2/T2, and I did that and got .001356, which isn't right. Can someone help please?

At a fixed temperature and number of moles of nitrogen gas, its volume and pressure are 368 mL and 668 torr, respectively. What is the final pressure in torr, if the final volume is 260 mL?

This is P1V1=P2V2. I got 1.244, which is also wrong. Why?
