Consider the net reaction for the methanol fuel cell. Based on the bonds broken and formed in the reaction, calculate the net free energy of this reaction. Based on this value, calculate the theoretical cell potential for your methanol fuel cell.
Problem- Carry out the following calculation, making sure that your answer has the correct number of significant figures
A 0.003525-mol sample of an organic compound was burned in oxygen in a bomb calorimeter. The temperature of the calorimeter increased from 24.5oC to 26.7oC.

Calculate the concentration of chloride ions in a saturated lead(II) chloride (Ksp = 2.4 ? 10-4) solution.
prepare 100 mL each of five standard solutions: 2.00 x 10-5, 5.00 x 10-5, 1.00 x 10-4, 2.00 x 10-4, and 5.00 x 10-4 M. These will serve as your analytical standards, which means that their phosphate concentrations must be precisely known.
