Question

7.
The density of a gas is 10 times more than that of hydrogen. Molecular weight of gas X is
8.
Total number of hydrogen atoms in 4.9 g of sulphuric acid is​

Answer 1

Answer:

Well what I've done up to now is this:

The molecular mass of hydrogen is M(H2)=2, the density of hydrogen is ρ(H2)=0.089 kg/m3. Assuming that equal volumes V of both gases are taken, the mass of hydrogen m(H2)=(0.089⋅v)kg and the mass of the unknown gas m(X)=(0.89⋅v)kg.
