Ten grams of a gas occupies 12.5 liters at a pressure of 42.0 cm Hg . What is the volume when the pressure has increased to 75.0 cm Hg? none of the above 7.00 L 8.00 L 6.00 L

To solve this problem, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional when temperature and the amount of gas are held constant. Mathematically, Boyle's Law is expressed as: Where:- and are the initial pressure and volume.- and are the final pressure and volume.Given:- cm Hg- L- cm HgWe need to find .Using Boyle's Law: Solving for : Therefore, the volume when the pressure has increased to 75.0 cm Hg is 7.00 liters. The correct answer is:7.00 L
