Which of the following solutions does have a greater solute concentration in molality (m)? Solution (1) 5.00-g glucose (molar mass: 180.2 g/mol) mixing with 20.0-g water. Solution (2) 1.00-g ethylene glycol (molar mass: 62.07 g/mol) mixing with 10.0-g water. Note both glucose and ethylene glycol are non-electrolytes. Solution (1) Solution (2) same concentration for both soluitons insufficient information to answer the question.

Note: This is an algorithm question so each attempt will have unique set of measurements. The following results were obtained when a sample of white cranberry juice was analyzed to determine its Vitamin C content. A 82.0 mL sample of the juice was placed in a flask with excess H2SO4, excess KI, and 11.00 mL of 0.07 000 M KIO3. Titration with thiosulfate solution required the use of 1.63 mL of 0.08826 M. Calculate the concentration of Vitamin C in the juice sample as mg Vit C per 100 mL juice. Here are some steps to help you work your way along the problem. All the reactions in the Background apply. • How many total millimoles of I are produced from the Reaction 4 between KI and KIO3? • How many millimoles of I are consumed in Reaction 3 with thiosulfate? . Using your previous two answers, how many millimoles of I reacted with the Vitamin C in the juice? • How many milligrams of Vitamin C were in the juice sample? • What is the concentration of Vitamin C in the juice sample expressed as…

The percentage purity of a paracetamol sample was determined by a reversed phase HPLC method as follows: • A calibration curve of peak area versus concentration (ug/mL) of pure paracetamol was constructed The paracetamol sample for analysis was prepared by taking 10.0254 g of powder and dissolving it in IL of distilled water (solution A). 1 mL of the latter solution was further diluted to 1L with distilled water (solution B). Solution B was analysed by HPLC analysis Results • The equation for the best-fit line of the calibration curve is: y = 26811x – 1313.8 The average peak area for the paracetamol sample (solution B) was 266796.2 Calculate the percentage purity of the paracetamol powder.
