Answer:

1.

   Mss of solute : 25g

   Mass of solution: 250 g

M%= (mass of solute/mass of solution)(100%)

      =(25g/250g)(100%)

      = (0.1)(100%)

      = 10% is the percent by mass of salt in the saltwater

2.

   Mss of solute : 3.5g

   Mass of solution: 500g

M%= (mass of solute/mass of solution)(100%)

      =(3.5g/500g)(100%)

      = (0.007)(100%)

      = 0.7 % is the percent by mass of cofee powder in the water

3.

   Mss of solute : 125g

   Mass of solution: 950 g

M%= (mass of solute/mass of solution)(100%)

      =(125g/950g)(100%)

      = (0.1316)(100%)

      = 13.6% is the percent by mass of sugar in the water
