Question

You need to fill up a basketball that's low on air pressure. It's initially at a pressure of 6 psi, and you want to inflate it to 7 psi so that it is properly inflated. The volume of the ball is 7000 cubic centimeters, and you can assume that the volume of the ball remains constant as you pump air into it. What is the initial mass of air in the ball, if you assume that the air in the ball is at the ambient temperature of 298 K and that the ideal gas relations hold true for the air in the ball? 0.47 g 0.12 g 3.3 g 3.8 g You need to fill up a basketball that's low on air pressure.
