    Answer: 236.7352 g

    Explanation:

    volume = 3.502 L, Concentration = 2.6 mol/L, Mass of solution = 26 g/mol

    Concentration = amount/volume

    To get the amount of solution, we make amount the subject of formula. We thus have

    Amount = Concentration * Volume = 2.6 * 3.502 = 9.1052 mol

    To get how many grams of solution was dissolved in the solution, we use the formula

    Mass of solute = Amount * Mass of solution

    = 9.1052 * 26 = 236.7352 g

    There is 236.7 grams dissolved

    Explanation:

    Step 1: Data given

    Volume of solution = 3.502 L

    Concentration of the solution = 2.6 mol/L

    Molar mass of the solution = 26 g/mol

    Step 2: Calculate moles

    Number of moles = concentration * volume

    Number of moles = 2.6 M * 3.502 L

    Number of moles = 9.105 moles

    Step 3: Calculate mass

    Mass = moles * molar mass

    Mass = 9.105 moles * 26 g/mol

    Mass = 236.7 grams

    There is 236.7 grams dissolved
