Pls do fast and i will give like for sure Try to give solution in typed form

A prototype sports ball for a new game is precisely inflated to a pressure of 7.3 psi at 25 degrees C. The ball is spherical with an inner bladder diameter of 22.8 cm. It is filled with air (Mw=28.97 g/mol). Not Avogadro’s number is 6.022 x 10^23 atom/mol. A. Calculate the number of moles of air in the ball at the specified temperature and pressure. Consider the air in the ball to follow the ideal gas law. PV=nRT   Where P is the absolute pressure of the air in atm, V is the volume of the ball, T is the absolute temperature in K, and R is the ideal gas constant.   B. How many oxygen atoms compose the air in the ball? Assume that the mole fraction of N2 in the air is 0.79 and the remainder of the air is 02(oxygen).

1. Which gas has the lowest kinetic energy at 330 K and under a pressure of 1.00 atm? a) N₂ b) Co c) CS₂ d) the gases have the same kinetic energy
