Two liquids are added to the same graduated cylinder. liquid a has a mass of 10g with a volume of 5ml. liquid b has a mass of 15g with a volume of 10ml. which liquid would end up on the top when they are combined

Answer : The correct answer is Liquid B will remain at top.

When two liquid are combined , they settle on the basis of their densities . The liquid with lower density will remain at top while the liquid with higher density will settle at bottom .

So we will calculate densities of two liquids. The formula to calculate density is

Density = mass / volume

GIven : Liquid A => mass = 10 g volume = 5 mL

Density = 10 g / 5 mL

Density = 2 g/mL

Liquid B => mass = 15 g volume = 10 mL

Density = 15 g / 10 mL

Density = 1.5 g/mL

Hence density of Liquid A is greater than Liquid B, so the liquid B will remain at top of graduated cylinder when they are combined.
