- Which unknown solution contains the highest concentration of sucrose? Three lab groups carried out an experiment to identify the concentration of sucrose in six solutions. Each unknown solution (1-6) contained one of the following sucrose concentrations: 0.0 M, 0.2 M, 0.4 M, 0.6 M, 0.8 M, and 1.0 M. Cubes of sweet potato (1 cm3) were soaked for 24 hours in each solution and weighed to determine the change in mass. Each data entry represents the average of three sample replicates expressed as percent change in mass following a 24-hour soak in the unknown solutions. Unknown Percent Change in Mass Percent Change in Mass Percent Change in Mass Group 1 Group 2 Group 3 1 6.6 7.8 7.5 2 3.1 3.7 2.9 3 -2.7 -3.5 -2.5 4 0.7 0.5 1.1 5 -11.6 -12.3 -12.6 6 -5.2 -6.2 -4.9 Which unknown solution contains the highest concentration of sucrose? a) 3 b) 4 c) 5 d) 1For each solution, calculate the rate of weight change over this 30-minute period. Write your answer in standard notation and use 3 digits past the decimal point 0.0 M sucrose = ____________________ g/min 0.4 M sucrose = _____________________ g/min 0.6 M sucrose = _____________________ g/min 0.8 M sucrose = _____________________ g/min 1.0 M sucrose = _____________________ g/min Time (min) 0M sucrose 0.4M sucrose 0.6M sucrose 0.8 M sucrose 1.0M sucrose 0 4.36 g 4.59 g 4.7g 4.5 g 5.0 g 15 4.5 g 4.3 g 4.4 g 4.1 g 4.6 g 30 4.6 g 4.2 g 4.0 g 3.7 g 4.0 gGiven the following information, calculate the total activity in the undiluted protein sample.
