1. The problem statement, all variables and given/known data An ideal gas is stored in a cylinder whose volume is unknown. Part of this gas is transfered to another cylinder whose volume is 300 cm3 and pressure is 790 mmHg. The mass loss caused the pressure in the first cylinder to decrease from 650 to 630 mmHg. Considering that all measurements were taken at constant temperature, calculate the volume of the cylinder. 2. Relevant equations PV=nRT PV=k I just can't get it started. Thank you in advance!
