2. Answer the following problems using GRESA method in a piece of paper. 1. A 63% salt solution has a volume of 475mL. How many grams of salt does it contain? 2. How much water is in 950ml of 35% solution? 3. How much water is in 830ml of 85% solution? 4. How much alcohol and water is in 810ml of 55% solution? 5. How much alcohol and water is in 1,500ml of 40% solution?
Answer:
1. To determine the amount of salt in a 63% salt solution with a volume of 475mL, we need to multiply the volume by the percentage of salt in the solution and then convert the result to grams.
The calculation is:
475 mL x 63/100 = 299.25 mL of salt (assuming the volume is measured in milliliters)
The density of salt is approximately 2.16 g/mL, so:
299.25 mL x 2.16 g/mL = 645.54 grams of salt.
Therefore, 475mL of a 63% salt solution contains 645.54 grams of salt.
2. To determine the amount of water in a 35% solution with a volume of 950mL, we need to subtract the amount of solute (in this case, whatever is not water) from the total volume.
The calculation is:
950 mL x (100% - 35%) = 617.5 mL of water.
Therefore, 950mL of a 35% solution contains 617.5mL of water.
3. To determine the amount of water in an 85% solution with a volume of 830mL, we again need to subtract the amount of solute from the total volume.
The calculation is:
830 mL x (100% - 85%) = 124.5 mL of water.
Therefore, 830mL of an 85% solution contains 124.5mL of water.
4. To determine the amount of alcohol and water in an 810mL solution that is 55% alcohol, we need to use the same method as in the previous examples, but this time we need to find the amount of both alcohol and water.
The calculation is:
810 mL x 55/100 = 445.5 mL of alcohol
810 mL - 445.5 mL = 364.5 mL of water
Therefore, 810mL of a 55% solution contains 445.5mL of alcohol and 364.5mL of water.
5. To determine the amount of alcohol and water in a 1,500mL solution that is 40% alcohol, we can use the same method as in example 4.
The calculation is:
1,500 mL x 40/100 = 600 mL of alcohol
1,500 mL - 600 mL = 900 mL of water
Therefore, 1,500mL of a 40% solution contains 600mL of alcohol and 900mL of water.
3. 2. Stacy can drink 5 glasses of milk per week. If each glass contains 475ml of milk, how much milk does she drink a week? Let x be the number of mL of milk.
Answer:
x = 2375 mL of milk per week
Step-by-step explanation:
x = ?
= 5 • 475mL
= 2375 mL
