Question 58

The concentration of a solution can be calculated using the equation:

concentration of solution=mass of dissolved solidvolume of solution \text{concentration of solution} = \frac{\text{mass of dissolved solid}}{\text{volume of solution}} concentration of solution=volume of solutionmass of dissolved solid​

An environmental engineer collected an 80 cm3 wastewater sample from an industrial runoff channel. The sample was analyzed and found to contain 7.36 g of dissolved metal salts.

Use the equation to calculate the concentration of dissolved metal salts in this sample in g dm−3\text{g dm}^{-3}g dm−3.
