Question

 A solution contains 80g of calcium chloride in 390g of water.Calculate the concentration of the solution​

Answer 1

Answer: 11.1% IS THE ANWSER

Explanation:

Mass (solute) = 40 gram

Mass (solvent) = 320 gram

Mass (solution) = Mass (solute) + Mass (solvent)

                        = 40 gram + 320 gram

                        = 360 gram

∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)] × 100

                                = [40/360] × 100

                                = 11.1 %

Answer 2

Answer:

percentage =mass of solute / mass of solution *100

Explanation:

percentage =80/470*100=800/47. the percentage =17.07 %
