For the titration we use the equation,

M₁V₁ = M₂V₂

where M is molarity and V is volume. Substituting the known values,

(0.15 M) (43.2 mL) = (2) (M₂) (20.5 mL)

We multiply the right term by 2 because of the number of H + in H2SO4. Calculating for M₂ will give us 0.158 M. Thus, the answer is approximately 0.16M.
