Calculate the mass of 4.50 moles of chlorine gas cl2

A sample of chlorine gas has a mass of 39.2 grams. - Socratic
Also, I calculated #70.9# because #35.45 " g/mol"# (themassof one Chlorine atom) times #2# is #70.9 " g/mol"# (Cl2 has two Chlorine atoms).

Use the ideal gas law: PV = n RT to calculatemolesofCl2. You will neeed to convert your pressure to atm and your temperature to Kelvin and use 0.08206 Latm/molK for R. Then, multiply molesCl2 by the molarmassofCl2 to convert moles into grams.
