Question

What mass of potassium chloride should be dissolved in a `500*mL` volume of aqueous solution to give a concentration of `1*mol*L^-1`?

Answer 1

Approx. `37*g`.....

Explanation:

`37*g` of salt could be dissolved in a `500*mL` volume of water to give a `1*mol*L^-1` solution with respect to `KCl`. Its purity depends on the purity of the salt you use to make it.
