A. There are 28 g of salt dissolved in 400 ml of water. Consider the quantity 0.07 = 28/400.

1. Give the name of the quantity if there is one.

2. What is the interpretation of . 07 g in this context?

3. Use the interpretation to find the amount of salt dissolved in 19 ml of the same solution

1. The quantity 0.07, or 28/400, is a concentration.

2. In this context, the interpretation of 0.07 g is that it represents the amount of salt present in 1 ml of the solution. It tells us how much salt is dissolved in each unit of volume.

3. To find the amount of salt dissolved in 19 ml of the same solution, you can multiply the concentration (0.07 g/mL) by the volume of the new solution (19 ml):

Amount of salt = Concentration x Volume
Amount of salt = 0.07 g/mL x 19 mL

To calculate this, multiply 0.07 by 19 to get the amount of salt dissolved in 19 ml of the same solution.
