An empty container has a mass of 50 g. When it is completely filled with a liquid of density 25 g/dm³, the total mass becomes 100 g. What is the volume of the container?

1. 0.25 dm³
2. 0.5 dm³
3. 1 dm³
4. 2 dm³

Correct answer: 2 dm³

Solution

The liquid mass is 100 - 50 = 50 g, and with density 25 g/dm³, volume = 50/25 = 2 dm³.
