Question

calculate the mass of krypton in a 1.46 litre cylinder at 47.3 degree Celsius and 7.87 bar​

Answer 1

Explanation:

We use the old Ideal Gas equation...

#n=(PV)/(RT)=(2.99*atmxx2.74*L)/(0.0821*(L*atm)/(K*mol)*331.9*K)#

#=0.301*mol#...

And we know (how) that krypton has a molar mass of #83.8*g*mol^-1#...

And so we take the product...…..

#0.301*molxx83.8*g*mol^-1=??*g#
