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.
