how much water can dissolve in 700ml of water at 50 c?
Like dissolves like.
To determine how much water can dissolve in 700ml of water at 50°C, we need to consider the concept of the solubility of water at that temperature. Solubility is defined as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
In the case of water, it is commonly considered the solvent, so we would be looking at the solubility of a solute in water. However, in this question, you are asking about the solubility of water in water. Water is a highly polar molecule, and it is known to readily dissolve in itself. Therefore, we can say that the solubility of water in water is unlimited, meaning that any amount of water can dissolve in water.
So, in summary, 700ml of water at 50°C can dissolve an unlimited amount of water since water is capable of dissolving in itself without any limitations.
