Explanation:
We're asked to identify the gas based on some gas measurements and it's mass.
What we can do is find the molar mass
where
dd is the density of the gas, in"g/L"g/L . We're given that44 "g"g occupies2.82.8 "L"L , so the density is
(4color(white)(l)"g")/(2.8color(white)(l)"L") = 1.434lg2.8lL=1.43 "g/L"g/L
-
RR is the universal gas constant, equal to0.082057("L"•"atm")/("mol"•"K")0.082057L∙atmmol∙K -
TT is the absolute temperature of the gas, in"K"K . Standard temperature is defined as273.15273.15 "K"K -
PP is the pressure of the gas, in"atm"atm . Standard pressure is usually for these types of problems defined as11 "atm"atm
Plugging in known values, we have
