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
