Answer:
By space using space gas space law space

fraction numerator straight P subscript 1 straight V subscript 1 over denominator straight T subscript 1 end fraction equals fraction numerator straight P subscript 2 straight V subscript 2 over denominator straight T subscript 2 end fraction

We space will space get comma
straight V subscript 2 space equals space 136.5 space ml
space space space space space space equals space 0.546 space straight g

Mass space of space 136.5 space ml space equals space 0.546 space straight g
Mass space of space 1000 space ml space equals space fraction numerator 1000 cross times 0.546 over denominator 136.5 end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 4 space straight g.
We space know space

VD equals space fraction numerator Mass space of space 1 space lit space of space gas over denominator Mass space of space 1 space lit space straight o space straight H subscript 2 end fraction

space space space space space space space equals space fraction numerator 4 over denominator 0.09 end fraction

space space space space space space space space equals 44.44

Relative space Molecular space Mass equals 2 space cross times VD


space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 2 cross times 44.44

Relative space Molecular space Mass space equals 88.88
