A

`83.9`

B

` 95.6`

C

` 91.6`

D

`87.4`

To find the solubility of potassium nitrate (KNO3) at 50°C, we will follow these steps: ### Step 1: Calculate the weight of the saturated solution. The total weight of the dish with the saturated solution is given as 108 g, and the weight of the empty dish is 39 g. \[ \text{Weight of saturated solution} = \text{Total weight} - \text{Weight of empty dish} \] ...
