Aspirin is less soluble than table salt, but more soluble than carbon dioxide.; A saturated solution of table sugar is more concentrated than a saturated solution of table salt.

Question 6

The solubility of glucose at 30°C is 125 g/100 g water. A solution is made by adding 250 g of glucose to 100 mL of water at 30°C. Remember that 1 g water = 1 mL water. How would you classify this type of solution?
