Question

0.11: Calculate the density of CH4 and H2 gases at 27°C and 25 atm​

Answer 1

Explanation:

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

Answer 2

Answer:

Here, T=27⁰

C=27+273=300K

P=25 atm

The molar mass of(M) CH4 = 16g/mol

From ideal gas equation,

d= PM/RT

= 25×16/0.0821×300

= 16.24g L −1.

Here, T=27⁰

C=27+273=300K

P=25 atm

The molar mass of(M) H2 = 1.00784g/mol

From ideal gas equation,

d= PM/RT

= 25×1.00784/0.0821×300

= 1.0229g L −1.
