A jar contains 30 mL of glycerin (mass=37.8 g) and 60 mL of corn syrup (mass=82.8 g). Which liquid is on the top layer? Explain your answer.

less dense material comes up. glycerin dencity = 37.8 / 30 syrup density = 80 / 60 so glycerin is less dense and comes up

Glycerin

Explanation:

Applying the concept of density, the less dense material stays at the top while the more dense material stays below in the glass.

Density (ρ) = mass / volume

Density of glycerin = 37.8 / 30*10⁻³ = 1260g/l

denisty of corn = 82.8 / 60 * 10⁻³ = 1380g/l

from the above calculation, it shows that maize has the highest density and would stay below glycerin in the jar.
