    answer:

    a. 195.06 g

    b. 2.11

    elaborate your question on letter b, i've got the answer on that one by using the formula of percent weight by weight (%w/w)

    %w/w = weight solute/weight volume

    a. 5.35 moles of solute

    b.0.00616 mol sucrose

    Explanation:

    a.)

    step 1: list all given variables

    Volume = 1.25 L

    Molarity = 4.28 M

    Step 2: calculate the unknown

    Molarity= mole of solute/Liter of solution

    Mole of solute = molarity x liter of solution

                = 4.28 M x 1.25 L

                = 5.35 moles of solute

    b.)

    step 1: list all given variables

    mass of solution = 85.3 g

    mass % sucrose = 2.47 %

    step 2: calculate the unknown

    2.47%×1/100×85.3g×(1 mol sucrose)/(342.2965 grams sucrose)=0.00616 mol sucrose
