Question

A 80.0 mL sample of nitrous acid of unknown concentration is titrated with 36.2 mL of 1.45 M barium hydroxide. Determine the concentration of the acid solution.

Answer 1

Answer: 0.66 M

Step-by-step explanation:

`M_(A)V_(A)=M_(B)V_(B)\\(80.0)M_(A)=(36.2)(1.45)\\M_(A)=((36.2)(1.45))/(80.0) \approx \boxed{0.66 \text{ M}}`
