Question

calculate mortality of KCL solution having 12.4 gm dissolved in 282.2 ml solutions​

Answer 1

Answer:

0.5771 M

Explanation:

here you written mortality spelling mistake I'm taking it as Molarity.

Molarity = moles of solute / volume of solution in Litre

mass of KCl = 12.4 g

=> moles of KCl = mass / molar mass = 12.4 g / (74.55 g/mol) = 0.1663 mol

volume of solution = 282.2 mL = 0.2822 L ( since 1000 mL = 1 L )

So Molarity = 0.1663 mol / 0.2822 L = 0.5771 M

Thank you!
