What mass, in grams, of chlorine gas (Cl) is contained in a 15.5 liter tank at 25.5 degrees Celsius and 1.98 atmospheres? Show all of the work used to solve this problem.

anonymous · Answer

$$n=(1.98 atm*15.5L)/(0.08206Latm*298.65K)$$

There, the ideal gas equation is all set up for you to obtain the number of moles of chlorine gas.  Then, you must use the molar mass of chlorine gas, Cl2 remember, to convert the moles to mass in grams.

anonymous · Answer

(V)Volume = 22.41L
(T)Temperature = 273K or 0.0 Celsius
(P)Pressure = 1.0atm  
R value is always .08206 with atm
n = moles

V = nRP/K 

sub what you have into the equation

anonymous · Answer

Ignore the variables as they corrospond to standard temperture and pressure

anonymous · Answer

once you have the moles its as easy as using the formula
moles = grams/Molecular Mass

anonymous · Answer

appy formula for ideal gas as PV=nRT
