    Explanation:

    1, Formula

    Mass percent = (mass of solute/mass of solution) * 100

    2. Determine mass of solution

    Substitute the data and clear the mass of solution:

    3.5 = (3.0g / mass of solution) * 100 0.035 = 3.0g / mass of solution mass of solution = 3.0 g / 0.035 mass of solution = 85.714g

    3. Determine the mass of solvent:

    mass of solvent = mass of solution - mass of solute mass of solvent = 85.714g - 3.0g = 82.714g

    Round to two significant figures: 83 g
