Question

28.The density of CO2 gas is 1.76 g/L at 27°C and 750
mm pressure. At what pressure will the cO2 gas have
density twice this value, the temperature is kept
1500mm
constant?
​

Answer 1

Answer:

Here, T=27

∘

C=27+273=300K

P=2.5 atm

The molar mass of(M) CO

2

=44g/mol

From ideal gas equation,

d=

RT

PM

=

0.0821×300

2.5×44

=4.46 g L
