```							First of all calculate no.  Of moles of sulfuric acid added by div given mass by molar mass of acid that is 98 Then find concentration simply by formula Then use pH = - log(H+)  to get the answer as=log(-0.05) I think it would work

```							Molecular mass of H2 SO4 Sulfuric acid = 98Num of moles = 0.490 /98 = 0.005Volume of solution = 0.100 LMolarity = 0.005/0.100 = 0.050 MThere are 2 ions of H+ for each molecule of the acid. So[ H⁺ ] = 0.100 MpH = - Log₁₀ [ H⁺ ] = 1
