Question

For 196gm of H2SO4 find:
1.Mole of H2SO4 2.No.of molecules of H2SO4
3.Mole of H,S,O atom
4.No of H,S,O atom
5.No.of protons in H,S,O

Answer 1

Answer:

please mark me as a brain list

Explanation:

Weight of H

2

SO

4

=w=49g

Molar mass of H

2

SO

4

=M=98g/mol

∴ number of moles of H

2

SO

4

=n=

M

w

=

98

49

=0.5

There are 7 atoms in the H

2

SO

4

∴ total number of atoms =7×n×6.022×10

23

=7×0.5×6.022×10

23

=7×3.02×10

23

Hence, the correct option is (D).
