Answer: The molarity of the solution comes out to be 19.19 M.

Step-by-step explanation:

We are given:

99% m/m . This means that 99 grams of sulfuric acid is present in 100 grams of solution.

Density of solution = 1.9 g/mL

To calculate the volume of the solution, we use the equation:

Density of solution = 1.9 g/mL

Mass of solution = 100 g

Putting values in above equation, we get:

To calculate the molarity of a solution, we use the equation:

Given mass of sulfuric acid = 99 g

Molar mass of sulfuric acid = 98g/mol

Volume of solution = 52.63 mL

Putting values in above equation, we get:

Hence, the molarity of the solution comes out to be 19.19 M.
