Aqueous sulfuric acid (H2SO4) will react with with solid sodium
hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and
liquid water (H2O). Suppose 23. g of sulfuric acid is mixed with
24.8 g of sodium hydroxide. Calculate the minimum mass of sulfuric
acid that could be left over by the chemical reaction. Be sure your
answer has the correct number of significant digits.
