Answer 1

Answer:

molecular mass of H2SO4 = 98 amu

                                            =98 g

mole of H in 98 gms of H2SO4 = 2 mole

mole of O in 98 gms of H2SO4 = 4 mole

mole of S in 98 gms of H2SO4  = 1 mole

 

no. of moles in 98 gms

1. for H -

      98  gms =2 mole

       1 gms = 2/98

      98 gms = 2/98× 98        

                       = 2 moles

   2. for O

       98 gms = 4 moles

        1 gms = 4/98

      98 gms = 4/98× 98

                     = 4 moles

   3. for S

       98 gms = 1 mole

       1 gms =1/98

       98 gms = 1/98× 98

                       =  1 mole

total no. of mole = 2+4+1

                            = 7 mole
