Answer:
There are
Explanation:
In this problem, we need to find the number of molecules in
mol of
.
The molar mass of
is 
No of moles = mass/molar mass
We can find mass from above formula.

Also,
No of moles = no of molecules/Avogadro number

Hence, there are
Answer:
the oxidation number is zero because H=+1. S=-2
Explanation:
so two hydrogen and one sulphur so total no is zero
