Answer:
Liquid A
Step-by-step explanation:
If two liquids are mixed together, they will eventually separate based on their density. A liquid will float if it is less dense than the liquid it is placed in.
We are given two liquids, Liquid A and Liquid B.
Liquid A has a density of 2 g/mL
Liquid B has a density of 10 g/mL
2 is less than 10, therefore Liquid A is less dense than Liquid B.
We already established that the less dense liquid will float on top. Liquid A is less dense, so Liquid A will float on top.
