Question

calculate the molarity of 500g pure water​

Answer 1

Answer:

Molarity is a concentration term hence is independent of total amount of solution. 720g pure water means (720/18) moles or in other words 40 moles. Now density of water is 1g/mL hence volume of 720g water is 720 mL. Molarity is amount of moles of solute present in 1000 mL solution

hope it helps you

Answer 2

Answer:

5.55 M

Explanation:

Molarity of the substance don't change with respect the volume of the substance.
