Answer: The correct answer is g/mL.
Explanation:
Density is defined as the ratio of mass and volume of a given substance. The chemical equation used for calculating density is given as:
[tex]\text{Desnity}=\frac{\text{Mass of the substance}}{\text{Volume of the substance}}[/tex]
The units used to represent mass of a substance is 'g' and units used to represent volume of a substance is 'mL'.
Hence, the units for density will be g/mL.
