Answer:
H2
Explanation:
I would say H2 cause CH4 have less hydrogen gas .
Given :
Mass of
is 571.6 g per liter .
Density of solution ,
.
To Find :
a. Mass percentage
b. Mole fraction
c. Molality
d. molarity of H2SO4 in this solution.
Solution :
Molar mass of
, m = 1329 g/mol .
a ) Mass of
contain in 1 liter is 1329 g .

b ) Moles of
=
.
Moles of
=
.
Mole fraction
.
c ) Molarity of
.
Hence , this is the required solution .
The theory assumes that particles don't experience intermolecular forces. Thats right answer
