Question

given the molar mass of kcl is 74.5g/mol .show the detailed calculation for preparation of 600 ml of 750 ppm of potassium ion solution​

Answer 1

Answer:

Explanation:

In order to calculate the molarity of a solution, you need to know two things

the number of moles of solute present in solution

the total volume of the solution

The problem provides you with a

24.7-g

sample of potassium chloride,

KCl

, and a total volume of a solution of

500. mL

.

In order to find the number of moles of potassium chloride, your solute, use the compound's molar mass, which as you know tells you the mass of one mole of potassium chloride
