Question

A sample of powdered drink mix with a mass of 11.22 g is dissolved in water to make 250.00 mL of solution. 50.00 mL of the resulting solution is transferred to a new container and diluted to a total volume of 250.00 mL. How many grams of the drink mix powder are in the second solution?

Answer 1

Mass of powdered drink mix in 1 milliliter of Solution 1:
11.22/250.00=0.04 g
Mass of powdered drink mix in 50.00 milliliters of Solution 1 (transferred to Solution 2):
0.04·50.00 = 2.00 g
