QUESTION 40 You are experimentally determining the enthalpy of solution for an ionic compound using a coffee cup calorimeter. When you dissolve 32.14 g of the ionic compound (molar mass - 138 g/mol) in 409 g water in a coffee cup calorimeter, the temperature changes from 21.74°C to 15.89 °C. Calculate the enthalpy of solution (the enthalpy change when dissolving the ionic compound in water) in /mol. Use 4,184 18°C) for the specific heat capacity of the solution. Give your...

Question 1 2 pts 3.34 mL of an unknown glucose solution was diluted in a 100.00 mL of volumetric flask with distilled water. 10mL of that solution and 4.00 mL of the ferricyanide reagent was placed in a second 100.00 mL volumetric flask and diluted to the mark with distilled water. Spectrophotometric analysis of the glucose/ferricyanide solution showed that the concentration of glucose was 0.070 M. What is the concentration of glucose in the unknown solution?
