Question

Calculate the number of grams of COOH 3 CH in the vinegar.

Answer 1

If you are given the number of moles of sodium bicarbonate, use the balanced chemical equation. The molar mass of the acetic acid is 60 grams per mole. Using stochiometric balance.

 

Number of moles of acetic acid = 3 moles NaHCO3 (1 mol CH3COOH/1 mol NaHCO3) = 3 moles of acetic acid

Grams of acetic acid = 3 moles of CH3COOH (60 g CH3COOH/1 mol CH3COOH) = 180 grams of acetic acid
