Answer 2

Given : 8 litres of a 20% solution

To find : The amount of pure acid (in litres) in the given solution.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the amount of pure acid in the solution)

Here, the given statement (i.e. 8 litres of a 20% solution) means there is 20% of pure acid in a solution of 8 litres.

So, the amount of pure acid in the solution :

= (8 × 20%) litres

= [8 × (20/100)] litres

= 1.6 litres

(This will be considered as the final result of the given mathematical problem.)

Hence, the amount of pure acid is 1.6 litres.
