Hi, could I get some help with this macro-connection physics problem involving the Ideal Gas Law?
The set up is:
What is the average volume in nm3 (cubic nanometers) taken up by molecules of an ideal gas at room temperature (taken as 300 K), and 1 atm of pressure or 101325 N/m2 to 4 digits of precision if kB = 1.38e-23 J/K and 1 nm = 10-9 m?
Thank you.
