Answer 2

To find the mass fraction (W) of salt in the solution, we can use the formula:

W = (mass of salt) / (total mass of solution)

Given: Mass of salt (M) = 25 g Mass of water (m) = 75 g

Total mass of solution = Mass of salt + Mass of water Total mass of solution = 25 g + 75 g = 100 g

Now, we can calculate the mass fraction (W):

W = 25 g / 100 g = 0.25

The mass fraction of salt in the solution is 0.25, which is equivalent to 25%.
