A lab assistant prepared a potassium chloride solution for her class by dissolving 5.34 g of KCl in 152g of water. What is the mass percent of the solution she prepared?


Could you help me set this up/show me how to do this problem?

4 answers

mass fraction = g solute/g soln
5.34g/(152 + 5.34) then change to percent by multiplying by 100.
I got 3.39%, correct?
Thanks
3.40%
