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.

A 1 mL sample of glycogen was calculated to contain 35 µmol (micromole) glucose. To 1 mL of this sample was added 2 mL of 2 M HCL. It was then hydrolysed by boiling the solution for 15 minutes. After boiling the hydrolysate was cooled and made up with H2O to a final volume of exactly 10 mL. The glucose was measured in this solution and found to have a concentration of 570 µg/mL (microgram/milliliter). i) Calculate the mass (mg) of glucose in the 10 mL of hydrolysate. As the 1mL of glycogen sample was made up to a final volume of 10 mL, this mass of glucose was produced by the hydrolysis of the original 1 mL glycogen sample. ii) Calculate the amount (µmol) of glucose produced by the hydrolysis of the glycogen sample. iii) Calculate the purity of the glycogen used in the sample as % Purity = (moles of measured glucose/ moles of calculated glucose in glycogen) *100 iv) state your answer in a complete sentence.
A 1 mL sample of glycogen was calculated to contain 21 µmol (micromole) glucose. To 1 mL of this sample was added 2 mL of 2 M HCl. It was then hydrolysed by boiling the solution for 15 minutes. After boiling the hydrolysate was cooled and made up with H2O to a final volume of exactly 10 mL.

Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl). GIVENS: density of the oil = 0.9 g/mL each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.
In the phosphate analysis of a wastewater sample, 30.00 mL of the original sample was taken and diluted with 120.00 mL deionized water.

Identify and explain the mistakes made in the following laboratory protocols: A 10.00 mM solution of glucose (FW 180.16 g/mole) was prepared by first adding 180.16 mg of glucose to a 100 mL empty volumetric flask, and then DI H2O was added to the volumetric flask until the meniscus reached the 100 mL volume mark. The flask was capped and the solution vigorously mixed until the glucose completely dissolved.

An 80 kg subject consumed a snack that contained 50 g of carbohydrate. Before eating the snack the subject’s blood glucose was 5.5 mM. Calculate the concentration of glucose (mM) that would be reached in the blood after consuming the snack.Assume that all the carbohydrate in the snack was converted to glucose, rapidly absorbed and distributed throughout the extracellular water (ECW) within 30 minutes. Assume ECW is approximately 20% of body weight and the glucose is not metabolised further.
Tea leaves were boiled in water and around 1.50 grams of caffeine were extracted by 200.0 mL of water. If three portions of 25.0 mL of dichloromethane were used to extract the caffeine from the aqueous layer, how much caffeine will be extracted by the dichloromethane? Solubility of caffeine in water: 2.18 g per 100 mL waterSolubility of caffeine in dichloromethane: 18.2 g per 100 mL dichloromethane
