Final answer:
The density of an unknown liquid with a mass of 55 g and a volume of 5.5 ml is calculated using the formula Density = Mass / Volume, resulting in a density of 10 g/ml.
Step-by-step explanation:
The question asks about the density of an unknown liquid with given mass and volume. To find the density of the liquid, we use the density formula: Density = Mass / Volume.
With a mass of 55 g and a volume of 5.5 ml, the density calculation will be:
Density = 55 g / 5.5 ml = 10 g/ml
Therefore, the correct answer is A) 10 g/ml, which represents the density of the unknown liquid.
