Aqueous sulfuric acid (H2SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and liquid water (H2O).  Suppose 7.8 g of sulfuric acid is mixed with 9.92 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

Step 1

The balanced equation for the reaction of aqueous sulfuric acid with solid sodium hydroxide to produce aqueous sodium sulfate and liquid water is given as follows:

H SO.(aq)+2 NaOH (s)-Na SO. (aq)+2H20
1mole of H SO reacts with 2 molesof N2OH
