The mass of pure acetic acid in 220 ml of the given solution at 20°C is 92.311 g
<h3>What is Acetic acid?</h3>
Acetic acid is a type of carboxylic acid and also known as ethanoic acid
Its formula is CH₃COOH.
It is an organic compound and is a colorless liquid
It is mostly used in the production of vinegar
40 % acetic acid by mass means,
40 g of acetic acid is dissolved in 100 g of solution.
The density of solution at 20°C,
![\rho = 1.049 g/ml](https://tex.z-dn.net/?f=%5Crho%20%3D%201.049%20g%2Fml)
We know,
![\rho = \frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D)
![V = \frac{m}{\rho}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7Bm%7D%7B%5Crho%7D)
The volume of the solution,
= 95.33 ml
95.33 ml of solution contains 40 g of pure Acetic acid
220 ml of solution contains
= 92.311 g of pure Acetic acid
Thus, the mass of pure Acetic acid in 220 ml of solution at 20°C is 92.311 g
