If a saturated solution of NH4NO3 at 70 °C is cooled to 10 °C, how many grams of solute will separate if the quantity of the solvent is 126 g? (Use the data below.) Round your answer to three significant digits. solute 0TH 2001 600 500 400 300 200 100 NH4NO3 NaBr Nal NaOH Sucrose (table sugar) KCI Ce₂(SO4)3 NaCl 10 20 30 40 50 60 70 80 90 100 Temperature (°C)

A student task is to prepare 3 glucose (C6H12O6) solutions with different concentration. If the student must first prepare 100.0 mL of each solution. The student was given only 4.00 grams of glucose and 320.0 mL of water. At the end of the experiment, the student must end up with at least 80.0 mL of 0.200 M, 90.0 mL of 0.025 M, 100.0 mL of 0.0010 M glucose solution. The total volume of all of the solutions must not 320.0 mL solution. Be very specific.
