An ideal gas is contained in a cylinder with a volume of 5.0 102 mL at a temperature of 30.°C and a pressure of 710. torr. The gas is then compressed to a volume of 38 mL, and the temperature is raised to 827°C. What is the new pressure of the gas?

I'm sorry. You should use (p1v1/t1) = (p1v2/t2)

v1 = 500 mL

t1 = 30 + 273 = ?K

p1 = 710 torr

v2 = 38 mL

t2 = 826 + 273 = ?K

p2 = unknown
