5 grams of cereal was crushed and dissolved in 25 mL water and placed in a dialysis bag. This sample was dialysed over a week in a beaker which contains 500 mL of water. 5 mL of the dialysate (an aliquote from the 500 mL) was separated to determine the glucose concentration. The glucose concentration was determined as 5 mM. Calculate the amount (% w/w) of glucose present in the cereal. Hint: The molecular weight of glucose is 180.
