A Correct answer
Explanation

Mass by mass percentage = (mass of solute / mass of solution) * 100. Mass of solution = 50 + 350 = 400. Percentage = (50 / 400) * 100 = 12.5%.

AI explanation

The mass by mass percentage is calculated by dividing the mass of the solute by the total mass of the solution, then multiplying by 100. The total mass of the solution is the sum of the solute and the water, which is 50 g plus 350 g to equal 400 g. The concentration is therefore (50 / 400) * 100, which equals 12.5%.
