temperature, pressure and volume

Post by Diane »

If 18.0 g of O2 gas has a temperature of 350 K and a pressure of 550 mmHg, what is the volume?

O2 has a molecular weight 32, means 32 g at standard conditions http://en.wikipedia.org/wiki/Standard_c ... d_pressure will have a volume 22.4 L. Proportionally 18 g of O2 will have a volume 12.6 L, correct?
Now apply gas law and see how the volume changes at the different temperature and pressure.
Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
