G Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . Suppose 20. g of hydrochloric acid is mixed with 16.3 g of sodium hydroxide. Calculate the minimum mass of hydrochloric acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.

5.1 gram

Explanation:

To calculate the moles :

According to stoichiometry :

1 mole of require = 1 mole of

Thus 0.41 moles of will require=  of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

Moles of HCl left = (0.55-0.41) = 0.14

Mass of left =

Thus 5.1 g of hydrochloric acid  could be left over by the chemical reaction.
