A sample of hydrogen gas at a pressure of 0.694 atm and a temperature of 271 °C, occupies a volume of 417 mL. If the gas is heated at constant pressure until its volume is 626 mL, the temperature of the gas sample in °C will be?

Question

I got 407 °C but it says that is incorrect. What am I doing wrong?

Answer 1

(V1/T1) = (V2/T2)
Don't forget that T must be in kelvin.
