Homework Statement
At standard temperature and pressure (273 K and 1 atmosphere), oxygen has a mass density () of 1.43 kg/m3. The molecular mass (m) of oxygen is 32 u. Calculate the number (n) of molecules in one cm3 of oxygen. (Round to three significant figures.)
Homework Equations
R = 8.31 J/molK
kB = 1.38times10^-23 J/K
3.
I thought I had to use the following formula.. n=p(density not pressure)V/m.. When i put it in. it didnt get the right answer
PLEASE HELP
