## What is the molarity of the KCl solution?

One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

How will you prepare 5 ppm of KCl?

5 ppm means 5 g of solute in 106g of solution .

1. Mass of soln=20dm³ soln ×1000 g soln1dm³ soln =20 000 g soln.
2. Mass of Cl−=20000g soln ×5 g Cl−106g soln =0.10 g Cl−
3. Mass of KCl=0.10g Cl⁻ ×74.55 g KCl35.45g Cl⁻ =0.2 g KCl.

How do you calculate Molality of KCl?

1. Answer : The molality of KCl solution is 0.169 mole/Kg.
2. Solution : Given,
3. First we have to calculate the mass of solvent.
4. As we know, Mass of solution = Mass of solute + Mass of solvent.
5. Now we have to calculate the molality of KCl solution.
6. Formula used :
7. Therefore, the molality of KCl solution is 0.169 mole/Kg.

### What is the molar mass of KCl?

74.5513 g/mol
Potassium chloride/Molar mass
Answer and Explanation: The molar mass of a compound is calculated by multiplying the sum of the relative atomic mass Ar of the constituent atoms by the molar mass constant Mu . Where, Mr is the relative molar mass. Hence the molar mass of KCl is obtained as 74.5513 g mol−1 74.5513 g m o l − 1 .

What is the final concentration of chloride ions that remain in solution?

The concentration of chloride remaining is 9×10-10mol/L .

What is the total concentration of ions in a solution?

In addition, the total ion concentration is the sum of the individual ion concentrations. Thus for the 1 M NaCl, the total ion concentration is 2 M; for the 1 M CaCl 2, the total ion concentration is 3 M.

#### How do I make a 500 ppm solution?

500 ppm translates to 500 mg/L. Then you weigh 500mg of the solid pesticide, dissolve it in a small volume of distilled water and make the solution up to the one litre mark on a measuring cylinder.
