Asolution contains 100.0 g water, 10.0 g nacl, and 15.0 g methanol. what is the masspercent of methanol in the solution?

12% is the mass percent of methanol in the solution.

Explanation:

Mass of water = 100.0 g

Mass of NaCl = 10.0 g

Mass of methanol = 15.0 g

Mass of the solution = 100.0 g+ 10.0 g+ 15.0 g = 125.0 g

12% is the mass percent of methanol in the solution.
