Salt can be produced from seawater by evaporation. Suppose seawater consists of 60% mass of salt materials. The density of seawater is 1.2 kilograms/liter. Calculate the mass of salt produced if 100 liters seawater is completely evaporated.
Answer: 60% x 100 liter x 1.2 kg/liter = 72 kg
- formula is correct but without unit: full mark
- only 72 : 1.0
- only 72 kg: 1.5
- only formula but wrong answer: 1.0
