GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Density, Mass, Volume - Explained

The video tutorial explains how to calculate the density of a new liquid, C, formed by mixing two liquids, A and B, with known masses and densities. The instructor uses the mass-density-volume triangle to solve the problem, calculating the volumes of liquids A and B first, then finding the total volume and density of liquid C. The tutorial emphasizes the importance of understanding the relationship between mass, density, and volume, and how remembering these triangles can simplify problem-solving.

What is the density formula used to calculate the density of liquid C?

How do you calculate the total mass of liquids A and B?

What is the volume of liquid A when its mass is 140 grams and density is 0.7 grams per centimeter cubed?

What is the total volume of liquids A and B after mixing?

Explain the relationship between mass, density, and volume in the context of this problem.
