Question

Weight of 6.02 into 10 power 20 molecules of hydrogen is

Answer 1

Thank you for asking this question. Here is your answer:

6.02 × 10^23 molecules of N2 = 1 mole of N2

&  3.02×10^23 molecules of SO2

=1/2 moles of SO2

So mass of 1 mole of N2 =2×14=28g

and mass of 1/2 moles of SO2 =1/2×(32+16×2)

=1/2×64 = 32g

So total weight of the gaseous mixture

=28+32 = 60g
