Problem- 1) The density of oxygen gas (O2, M= 32.00 g/mol) in a new oxygen gas cylinder, measured at T= 20 degrees Celsius, is 0.1632 g/ml. Find the following-
a) The number density of oxygen molecules in the gas cylinder (in units of molecules /cm3).
b) The calculated pressure of gas in the cylinder, using the ideal gas law. Give your answer in units of at, to file significant figures.
c) The calculated pressure of gas in the cylinder, using the van der Waals equation. Give your answer in units of at, to four significant figures.
The van der waals coefficient for O2 are a =1.364 L^2*atm/mol^2, b=0.0319 L/mol
d) Which calculated value for pressure (ideal or van der Waals) do you expect to be closer to the true value for gas pressure for the conditions in the problem? Why?
I don't know how to reach these answers thus please show the steps, thank you!
