Answer key: Percent Solution worksheet

1. Solute to weigh out: 52.5 g
1. Take that percent of the total weight. That's how much solute to weigh out
  $\frac{10%}{100} \times 525 g$ $= 52.5 g$
2. The rest of the weight is solvent, the liquid you mix it into
  $525 g - 52.5 g$ $= 472.5 g$
2. Liquid solute to measure: 36 mL
1. Take that percent of the total volume. That's how many mL of solute to measure
  $\frac{9%}{100} \times 400 mL$ $= 36 mL$
2. The rest is roughly the solvent. Top up to the line, since mixed liquids may not add up exactly
  $400 mL - 36 mL$ $= 364 mL$
3. Solute to weigh out: 51.75 g
1. Take that percent of the total weight. That's how much solute to weigh out
  $\frac{9%}{100} \times 575 g$ $= 51.75 g$
2. The rest of the weight is solvent, the liquid you mix it into
  $575 g - 51.75 g$ $= 523.25 g$
4. Solute to weigh out: 72 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{12%}{100} \times 600 mL$ $= 72 g$
5. Solute to weigh out: 40.5 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{9%}{100} \times 450 mL$ $= 40.5 g$
6. Solute to weigh out: 48 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{8%}{100} \times 600 mL$ $= 48 g$
7. Solute to weigh out: 103.6 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{14%}{100} \times 740 mL$ $= 103.6 g$
8. Solute to weigh out: 66 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{12%}{100} \times 550 mL$ $= 66 g$
9. Solute to weigh out: 37.5 g
1. Take that percent of the total weight. That's how much solute to weigh out
  $\frac{10%}{100} \times 375 g$ $= 37.5 g$
2. The rest of the weight is solvent, the liquid you mix it into
  $375 g - 37.5 g$ $= 337.5 g$
10. Solute to weigh out: 27 g
1. Take that percent of the volume in mL. The answer is the grams of solute to weigh out
  $\frac{9%}{100} \times 300 mL$ $= 27 g$
