Class 12 NEET Chemistry Solutions Questions

H2SO4 is 98% by weight.
Weight of H2SO4=98g
Weight of solution = 100 g
∴ Volume of solution=

Mass

Density

=

100

1.80

mL
=55.55 mL=0.0555 L
Molarity of solution =

98

98×0.0555

M=18.02M
Let V mL of this H2SO4 are used to prepare
1 liter of 0.1 M H2SO4
∴ mM of concentration H2SO4=mM of dilute H2SO4
or, V×18.02=1000×0.1
or, V=

1000×0.1

18.02

=5.55mL
