Answer:
0.01 moles NaCl
Step-by-step explanation:
It seems that the given volumes are unnecessary information.
To find the moles NaCl, you need to convert moles HCl and NaOH to moles NaCl via the balanced chemical equation. Specifically, you need to use the mole-to-mole ratio made up of the reaction coefficients. The reason why you need to convert both reactants is because you have not been given a limiting reagent. The smallest amount of moles NaCl calculated will be the final answer.
The balanced reaction:
HCl + NaOH -----> NaCl + H₂O
0.1 moles HCl 1 mole NaCl
---------------------- x ---------------------- = 0.1 moles NaCl
1 mole HCl
0.01 moles NaOH 1 mole NaCl
----------------------------- x ----------------------- = 0.01 moles NaCl
1 mole NaOH
NaOH produces the smallest amount of product. This means it is completely used up before HCl runs out. Therefore, NaOH is the limiting reagent and 0.01 moles NaCl are actually produced.
