Multiple Choice

Hector is performing a chemistry experiment that requires 160 milliliters of 40% sulfuric acid solution. He has a 25% sulfuric acid solution and a 50% sulfuric acid solution. How many milliliters of each solution should he mix to obtain the needed solution?

• 60 mL of 25% solution

  100 mL of 50% solution

• 96 mL of 25% solution

  64 mL of 50% solution

• 80 mL of 25% solution

  80 mL of 50% solution

• 64 mL of 25% solution

  96 mL of 50% solution

Open Ended

Hector needed 96mL of 50% acid solution and 64mL of 25% acid solution to make 160 milliliters of 40% acid solution. Why does it makes sense that he needed a larger amount of the 50% acid solution?

Exit Ticket #1:

Michael is mixing 2 types of candy for a party. The chocolate pieces cost $0.40 per ounce and the hard candy costs $0.20 per ounce. Michael purchases 20 ounces of the chocolate pieces, and the total cost of the candy was $11. How many ounces of hard candy did he purchase? Pick the equation that represents this mixture problem.

• 0.4x + 0.2(20) = 11

• 0.4(20) + 0.2x = 11

• (0.4 + 0.2)x = 11

• 0.4 + 0.2 = 11x
