Question

What volume of 0.34 M KOH is sufficient to react with 20 ml of 0.15 M H2SO4

Answer 1

Known:
M₁=0,34 m
a₁=H₂SO₄⇒H₂ =2
V₂=20  mL
M₂=0,15 M
a₂=KOH⇒OH =1
Asked: V₁?
Answer:

Use dilution formula:
M₁.a₁.V₁=M₂.a₂.V₂
(0,34)(1)(V₁)=(0,15)(2).(20)
                V₁  =   6   
                         0,34
                       =17,6 mL
