Final answer:
The density of the solution is 2.2 g/mL.
Step-by-step explanation:
The density of a solution is calculated by dividing the mass of the solution by its volume. In this case, the solution has a mass of 22 grams and a volume of 10 mL. Therefore, the density can be calculated as:
Density = mass/volume = 22 g / 10 mL = 2.2 g/mL
So the correct answer is 2.2 g/mL.
