  1. 1L = 1000 ml
    3.2L = (1000x3.2)ml = 3200 ml
    100 ml solution contain 5.0 g of glucose
    3200 ml solution contai( 5.0g x 3200ml)/100 ml
    = 160 g
    Therefore,
    Mass is 160g
    We know that the energy value of carbohydrate in kcal is 4
    So, 160g x 4kCal/g
    = 640 kCal

  2. How much glucose is in the 3.2 L? That's
    5.0 g glucose x (3,200 mL/100 mL) = ? g glucose.
    Then each g glucose has 4 kcal.
    You finish.
