If all the water evaporates the reading on the scales will be equal to 25 grams
Explanation:
- due to evaporation there is removal of all the water which is present in a container. Only the solute particles which are present will result in the weight of the solution after evaporation.
- hence the weight of the solute which is present here is equal to 25 grams of the solute. Hence The final weight after evaporation of the entire volume of the water will be 25 grams of the salt.
