Solubility
Lower Sec Science · Secondary 1 · Hard · Solubility
A student prepares a saturated solution of a salt at 70 °C. At this temperature, the solubility is 60 g of salt per 100 g of water.
He cools the solution to 30 °C, where the solubility is 40 g per 100 g of water.
If he used 100 g of water, what mass of salt will crystallise out on cooling from 70 °C to 30 °C?
