Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water. If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?

114 gram of salt is required.

Explanation:

Below are the following given data in the question:

Prepared salinity water = 30 ppt

Weight of salt used = 3.26 kg

The volume of water = 114 L

Below is the calculation.

4000 mL = 4000/1000 = 4L

Let the used = x kg

3.26/114 = x/4L

Now solve for the x.

x = 0.114 kg or 114 gram
