calculate number of dichlorine molecules in a 5.00ml container at 40 degrees Celsius and a pressure of 2.14 x 10^4 Pa.

Use PV = nRT and calculate n = number of mols.
I would use P in atm and volume in L. T must be in kelvin. Then you know that 1 mol contains 6.02E23 molecules; therefore xx mol will contain ?? molecules. 
how do i convert Pa to atm?

1 atm = 101.325 kPa
