Question

To titrate 20.00 milliliters of an unknown HC2H3O2 sample, use 43.00 milliliters of a standard 0.1000 M NaOH titrant. What is the molarity of the HC2H3O2?

0.2150 M

0.1000 M

860.0 M

0.04651 M

Answer 1

So first step is to determine the number of moles of NaOH using the formula n=cv where n is the number of moles, v is the volume of NaOH in litres and c is the concentration which is the 0.1L

Answer 2

HC2H3O2 + NaOH >> NaC2H3O2 + H2O
acetic acid + sodium hydroxide >> sodium acetate + water
This is the chemical formula and it is balanced

Answer 3

thank you
