A chemistry student needs to determine the concentration of a sulfuric acid solution by titrating 25.0 mL of the acid with 0.1000 M sodium hydroxide. The reaction between the two substances is H2SO4 + 2NaOH → Na2SO4 + 2H2O. If it takes 35.0 mL of the sodium hydroxide solution to fully neutralize the sulfuric acid, what is the concentration of the sulfuric acid solution in moles per liter (M)?
