Question

a sample of sulphuric acid is 81.6% by mass and it has a concentration of 15 moles per litre. its density is given by​

Answer 1

Explanation:

Molarity = mass % × density × 10

density = 15 / 81.6×10 = 0.104 kg/lit

hope this will help you

Answer 2

Explanation:

Molarity is defined as the number of moles of an element or compound in 1L solution

As per given data, let us first calculate the number of moles of sulphuric acid is 15 moles per litre, which means its molarity is 15.

To determine the density given the mass percentage of acid, we use the below formula

Molarity = Percentage of mass × density × 100

Density = 15 / 81.6×100

             = 0.104 kg/lit
