Answer:
1.83moles
Explanation:
Given parameters:
Mass of methane given = 29.2g
Unknown:
Number of moles = ?
Solution:
To find the number of moles in this mass of a compound;
Number of moles =
Molar mass of CH₄ = 12 + 4(1) = 16g/mol
Now;
Number of moles = = 1.83moles

was there a question you needed help with?
We need to keep in mind that the compound is neutral.
H2SO3
2(+1)+S+3(-2)=0 (since its neutral)
2+S-6=0
S-4=0
S=4
Therefore the oxidation number for sulfur is +4.
