Topic: Concept 9.2 Skill: Knowledge/Comprehension 19) The free energy for the oxidation of glucose to CO 2 and water is -686 kcal/mole and the free energy for the reduction of NAD+ to NADH is +53 kcal/mole. Why are only two molecules of NADH formed during glycolysis when it appears that as many as a dozen could be formed?

Sep 02, 2009 · At a given temperature you have a mixture of benzene (vapour pressure of pure benzene = 745 torr) and toluene (vapour pressure of pure toluene = 290 torr). The mole fraction of benzene in the solution is 0.77. Assuming ideal behaviour, calculate the mole fraction of toluene in the vapour above the solution. Thanks a lot for the answer

Apr 10, 2016 · C N is the normal concentration in equivalents/L (Normal or N). This is also referred to as normality, which is used to express the concentration of a solute in a solution.. Normality is defined as the number of equivalents of solute dissolved per liter of solution (equivalents/L = N) (Equations 1, 3, and 2.1 Definition of mole :One mole is a collection of that many entities as there are number of atoms exactly in 12 gm of C-12 isotope. or 1 mole = collection of 6.02 × 1023species 6.02 × 1023= N A= Avogadro's No. ` 1 mole of atoms is also termed as 1 gm-atom, 1 mole of ions is termed as 1 gm-ion and 1 mole of molecule termed as 1 gm-molecule.
