Question

I got this wrong on a quiz and Im not sure why.

A gas sample is heated from -20 degrees C to 57.0 degrees C and the volume increased from 2.0 L to 4.50 L. If the initial pressure is 0.146 atm what is the final pressure?

My answer was .0498 and it was wrong.

Please explain step by step.

Thank You
