Please see the attached file. Provide step by step calculations for the problem.

How many alpha particles are emitted per minute by 1cm^3 of 222^Rn monoatomic gas at a temperature of 27 degrees Celsius and a pressure of 100 kPa? Make use of PV - NkT where P = pressure of the gas, V = volume of the gas, N = number of atoms in the gas, T = temperature of the gas in kelvin, and k = Boltzman's constant = 1.38 x 10^-23 J K^-1. The half-life of 222^Rn is 3.8235 days.
