Calculate the molarity of 10% by mass KC...

Calculate the molarity of 10% by mass `KCl` in water solution (molecular mass of `KCl=74.5g mol^(-1)`).

Text Solution

Verified by Experts

Number of moles of KCl in 100 g solution = 10/74.5 = 0.134 , Mass of solvent =90 g Molality `= (0.134 xx 1000)/(90) = 1. 49 m.`
