Answer 2

Answer:

Molar mass of SO2=32+2(12)

=64g/mol

No.of moles of Sulphur in 64g of SO2=64/64=1 mole

Molar Mass of SO3=32+3(16)

=80g/mol

No. of moles of Sulphur in 160g of SO3=160/80=2 mole

Molar mass of H2SO4=2+32+4(16)

98 g/mol

No. of moles of Sulphur in 196g of H2SO4=196/98=2 mole

Total moles=1+2+2

=5mole

in the form of NA=5×NA

5NA
