The density of the gas at given temperature and pressure

#="mass of gas"/"volume of the gas"=3.45/1.85" g/L"=1.865" g/L"#

By equation of state for ideal gas we know

#PV=w/MRT#

Where

#P->"pressure"=1.05atm#

#V->"volume"=1.85L#

#T->"temperature"=49+273=322K#

#R->"ideal gas constant"=0.082LatmK^-1mol^-1#

#M->"molar mass of the gas"=?#

#M=(wRT)/(PV)=(3.45xx0.082xx322)/(1.05xx1.85)=46.9gmol^-1#
