Answer

Explanation:

Step1: Locate temperature on x - axis

Locate 60°C on the x - axis of the solubility - temperature graph.

Step2: Find solubility value

Follow the vertical line from 60°C up to the orange line representing $Na_2HAsO_4$. Then, read the solubility value on the y - axis. The solubility of $Na_2HAsO_4$ at 60°C is approximately 65 g/100 g $H_2O$. Since the units in the options are g/100 mL of water and for dilute solutions density of water is 1 g/mL, 100 g of water is approximately 100 mL of water.

Answer:

65 g/100 mL of water
