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
