Aqueous sulfuric acid

H2SO4

will react with solid sodium hydroxide

NaOH

to produce aqueous sodium sulfate

Na2SO4

and liquid water

H2O

. Suppose 42. g of sulfuric acid is mixed with 20.0 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.

Please can you solve this problem using the EXACT atomic masses from the ALEKS periodic table and not the atomic masses from the Regular periodic table:? Thanks.
