Question

find the mass hydrogen sulphate in which 1.5055*10^24 molecules present?

Answer 1

Answer:245 gms

Explanation:

Hydrogen sulphate (H2SO4)---molecular weight=98

So one mole of any gas occupies 6.023*10^23 molecues

Implies 98 grams contain 6.023*10^23 molecules

Given nuber of molecules=1.5055^10^24=15.055*10^23 molecules

So mass of H2SO4=98*15.055*10^23/6.023*10^23=98*15.055/6.023

=== 245 gms
