Question 76

An aquarist prepares a saline solution for a marine quarantine tank. The concentration of salt in the solution can be calculated using the equation:

concentration of solution=mass of dissolved saltvolume of solution \text{concentration of solution} = \frac{\text{mass of dissolved salt}}{\text{volume of solution}} concentration of solution=volume of solutionmass of dissolved salt​

The aquarist dissolves 54.6 g of sea salt in distilled water to make a total solution volume of 1500 cm3.

Calculate the concentration of this solution in g dm−3\text{g~dm}^{-3}g dm−3.
