Please show all work and explain it.

The answers are 1) 2.3x10^7J and 2) 32. Thank you

For O2 at 25C and 1atm calculate: 1. the total translational kinetic energy of O2 molecules in an empty room 10m5m3m. 2. the ratio of the probability that O2 molecule has its speed in an infinitesimal interval dv located at 300m/s to the probability that its speed lies in an infinitesimal interval dv at 1000m/s. Hint: MO=16g/mol,R=8.3145J/molK,1atm=101325Pa
