Answer 2

Calculation of Water and Salt in a 15% Salt Solution

To calculate the amount of water and salt in a 400g 15% salt solution, we need to determine the mass of water and the mass of salt in the solution.

Let's assume that the 15% salt solution means that 15% of the total mass is salt, and the remaining 85% is water.

1. Calculate the mass of salt: - Mass of salt = 15% of 400g - Mass of salt = 0.15 * 400g - Mass of salt = 60g

2. Calculate the mass of water: - Mass of water = Total mass - Mass of salt - Mass of water = 400g - 60g - Mass of water = 340g

Therefore, in a 400g 15% salt solution, there are 340g of water and 60g of salt.

Please note that the calculations above are based on the assumption that the 15% salt concentration refers to the mass percentage of salt in the solution. If there are any additional details or assumptions, please let me know, and I'll be happy to assist you further.
