We will have to suppose that the 135 g of KI are dissolved in 100 g of water to answer the problem.
We are given some graphs.
According to the graph, at 5 °c a saturated solution of KI can contain 135 g of KI in 100 g of water.
Answer: A solution of KI containing 135 g of KI at a temperature of 5 °C is considered saturated.
