What is the density of 5.0 L of #NO_2# gas at 1.0 atm at 0.0°C?
1 Answer
Explanation:
We're asked to find the density of
To do this, we can use the equation
where

#M# is the molar mass of#"NO"_2# , which is#46.01# #"g/mol"# 
#P# is the pressure of the gas, in#"atm"# , given as#1.0# #"atm"# 
#R# is the universal gas constant, equal to#0.082057("L"•"atm")/("mol"•"K")# 
#T# is the absolute temperature of the gas, in#"K"#
Notice how the given volume measurement is not needed, because the density of a material does't change by increased volume (because quantity will also have increased).
The given temperature converted to Kelvin is
Plugging in known values, we have
