Answer:

23.97 grams.

Explanation:

First we convert 3.14 x 10²³ molecules into moles, using Avogadro's number:

  • 3.14x10²³ molecules ÷ 6.023x10²³ molecules/mol = 0.521 moles

Then we convert 0.521 moles of HCOOH into grams, using the molar mass of formic acid:

  • 0.521 mol * 46 g/mol =  23.97 g

The answer is 23.97 grams.
