If 33.6 grams of kcl are dissolved in 192 grams of water, what is the concentration of the solution in percent by mass? a. 21.2% kcl b. 5.71% kcl c. 14.9% kcl d.17.5% kcl

Answer is: concentration of the solution in percent is C. 14.9%.
m(KCl) = 33,6 g.
m(H₂O) = 192 g.
m(solution) = m(KCl) + m(H₂O).
m(solution) = 33,6 g + 192 g.
m(solution) = 225,6 g.
concentration of the solution in percent = m(KCl) ÷ m(solution) · 100%.
concentration of the solution in percent  = 33,6 g ÷ 225,6 g · 100%.
concentration of the solution in percent = 14,9%.

Igonna be honest i dunno that one srry

Ineed with this also i hope you understand it
