Question

Molar mass of H2so4

Answer 1

H2SO4

=2(H)+S+4(O)

=2(at.wt of H) +at.wt of S+4(at.wt of O)

=2(1)+32+4(16)

=2+32+64

=98

Molar mass of H2SO4 is 98.

Answer 2

Molar mass of H2SO4 =2(atomic.wt of H) +atomic.wt of S+4(atomic.wt of O) 
                                     =2+32+16×4
                                     =2+32+64
                                     =98 g/ mol
i hope its help you.
