Answer

Explanation:

Step1: Locate the curve

Locate the curve of $K_{2}Cr_{2}O_{7}$ on the solubility - temperature graph.

Step2: Find the solubility at 50°C

Find the solubility value on the $K_{2}Cr_{2}O_{7}$ curve at 50°C. From the graph, the solubility of $K_{2}Cr_{2}O_{7}$ in 100g of water at 50°C is approximately 18g.

Answer:

18 grams
