Question

If a certain sample of an ideal gas has a temperature of 88C andexerts a pressure of 9x10^4 Pa on the walls of its container, howmany gas molecules are present in each cm^3 of volume? Assume thatthe gas is ideal. R=8.314 J/mol*K, Avagadros number=6.022*10^23molecules/mol.

Im using PV=nRT and I think im doing something wrong when itcomes to going from mols to molecules...

Ive gotten to n=PV/RT and just cant get the right answer inmastering physics. Anything helps! Thanks!
