Question

Estimate the average distance between molecules in air at 0.0°C and 4.90 atm.

The answer is not anything from 1.90nm-2.0nm. I have tried them all. Please help.

Expert Solution

Step 1

Given temperature T=0.0 degree=273K

Pressure P=4.90 atm $= 4.90 \times 1.01 \times 10^{5} P a$

And we know that PV=nKT

where P is the pressure V is the volume n is the number of moles

K is the Boltzmann's constant T is the temperature
