Answer:
The concentration of the solution in percent by mass is 14.3%
Explanation:
Given:
Mass of KCl (solute) = 32.3 g
Mass of water (solvent) = 192 g
To determine:
Concentration of solution in % mass i,e. %(w/w)
Formula:
%w/w[tex]= \frac{Mass\ of\ solute}{Total\ mass\ of\ solution } *100\\[/tex]
Total mass of solution = solute + solvent = 32.3 + 192 = 224.3 g
%w/w = [tex]\frac{32}{224.3} *100 = 14.3%[/tex]
