At 650 degree C and a pressure of 690mm HG, the 0.927g sample has a volume of 194cm3.
How do I calculate the volume at the same temp but at a pressure of 760mm Hg?
Also, how do I calculate the volume at the same pressure but at a temp of 0 degree C?
if it is a gas, you can use the combined gas law.
change temsp to K.
