Final answer:

Solubility and Temperature The solubility of a given solid typically increases with temperature. In this case, all 50.00 g of the solid will dissolve in 100 g of water at 313 K based on provided solubility data. The option 'A only' correctly describes the scenario.

Explanation:

The statements being evaluated here are related to the solubility of solid X in water at different temperatures. Looking at the provided information: 21.0 g of X can dissolve in 100 g of water at 283 K, while 62.0 g can dissolve at 313 K. This indicates that the solubility of solid X increases with an increase in temperature, which is a common trend with many solids in water. When 50.0 g of X is introduced into 100 g of water at 313 K, it will be completely dissolved since the solubility at this temperature is greater (62.0 g). Thus, none of it will remain undissolved.

Therefore, the correct statements are: "A) All the 50.00 g of X will dissolve at 313 K" and "C) Solubility of X decreases with increase of temperature." However, statement C is incorrect because solubility actually increases with temperature. Hence, the correct answer is choice b). A only.
