chemistry
How many moles of gas must be forced into a 3.1L ball to give it a gauge pressure of 9.8psi at 22degrees C? The gauge pressure is relative to atmospheric pressure. Assume that atmospheric pressure is 14.5psi so that the total pressure in the ball is 24.3psi .

Calculate the pressure drop expected on hydrogenation of the mixture of 5.00 ml of cyclohexene and 35 ml of cylclohexane. I know I have to use PV=nRT but this is all I know we are starting at 60 psi of pressure. We also used hydrogen gas if that helps
