Question

Calculate the volume of concentrated sulphuric acid required to make 1 liter of 0.2N H2SO4. If density of concentrated H2SO4 is 1.83 gm/ml​

Answer 1

Explanation:

So 9.8g of sulphuric acid in 500 ml is 0.2M. According to the question, every 100g of the concentrated acid solution has 96g of sulphuric acid. Therefore, 10g of the concentrated acid will contain 9.8g of sulphuric acid .

The question also says that the density is 1.84g/ml, meaning that every millilitre of the solution weighs 1.84 g. So , on calculating, you will see that approximately 5.435ml contains 10g of the concentrated acid solution.

So basically , your answer is 5.435ml of concentrated acid solution, made up to 500ml gives a solution of sulphuric acid with a concentration of 0.2M
