A #15.62*mL# volume of monoprotic acid reached a stoichiometric endpoint with #16.49*mL# of sodium hydroxide whose concentration was #1.175*mol*L^-1#. What is the concentration of the acid?
1 Answer
Explanation:
We need (i) a stoichiometric equation,
And thus there is 1:1 equivalence between acid and base.
By definition,
And thus the PRODUCT,
And so we need (ii) molar quantities of acid and base.....
But given the 1:1 equivalence between acid and base, CLEARLY this molar quantity was contained in the original
And so (finally)......
And note that doing the calculation this way, i.e. dimensionally with units included, gives me the appropriate units if we set up the problem correctly.
