A 250 L vessel is evacuated and then connected to a 50.0 L bulb with compressed nitrogen. The pressure in the combined containers is 1672 mm Hg. If the temperature remained at 20 °C throughout the process, what was the initial pressure in the 50.0 L bulb?

Can someone please give me a detailed explanation of how to solve this?

P1V1=P2V2
P1*250=1672mmHg*(250+50)
solve for P1
2.64?
