D) 36.2 mL of 0.1105 M NaOH solution
Explanation:
We have the following chemical reaction:
HCOOH + NaOH → HCOONa + H₂O
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume
number of moles of HCOOH = 0.2 × 20 = 4 mmoles
From the chemical reaction we see that 1 mmole of HCOOH will react with 1 mmole of NaOH so 4 mmoles of HCOOH will react with 4 mmoles of NaOH.
volume = number of moles / molar concentration
volume of NaOH solution = 4 / 0.1105 = 36.2 mL

Answer:
Practical significance refers to the magnitude of the difference, which is known as the effect size. Results are practically significant when the difference is large enough to be meaningful in real life. ... Very small differences will be statistically significant with a very large sample size.
