100g
This would be considered a saturated solution if all 25g of KCl are completely dissolved in the 100g of water at 30 degrees Celsius.
If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.
100g of water is equal to 100g of ice in terms of weight, since they both have the same mass. However, the volume of the ice may be slightly larger due to the lower density of ice compared to water.
Approximately 34 grams of KCl can dissolve in 100g of water at 30°C.
To prepare a 40% potassium chloride solution in 100g of water, you would need to calculate the mass of potassium chloride required. Since the solution is 40% potassium chloride, that means 40g of the total solution mass must be potassium chloride. Therefore, you would need to add 40g of potassium chloride to the 100g of water to prepare the solution.

Heat of vaporization at 100 degrees C is 40.65 kJ/mol. 100g water * 1mol/18.015g = 5.55 mol 40.65*5.55 = 225.6452956 = 226 kJ if three sig figs.

No, it is not.
The solubility of sodium nitrate in water at 30 degrees Celsius is approximately 180g per 100g of water. Therefore, in 250g of water, approximately 450g of sodium nitrate can dissolve.
