Question

The solubility of copper chloride at 20 °C is 73 g/100 g of water. Kiera adds 100 g of copper chloride to 100 g of water, and stirs. What mass of copper chloride remains undissolved? Select the one correct answer. 27 g 100 g 73 g 100 g

Answer 1

Answer: 27 g

Explanation: Assuming the temperature is 20 °C, only 73g of copper chloride will dissolve in 100g of water, so 100 - 73 = 27 g of copper chloride remains undissolved.
