mmol/l or mmol/L millimole per liter, the SI unit in medicine for measuring concentrations of substances in the blood. For example, it is known that combustion of exactly 1 g of benzoic acid, C 7 H 6 O 2, in a bomb calorimeter produces 26.38 kJ of heat. Suppose that 1.000 g of benzoic acid is combusted in a calorimeter and it causes a temperature increase of 4.857°C. The heat capacity of the calorimeter is then given by C cal = 26.38 kJ/4 5) The molar mass is 96.08582 g/mol.

For FCC, n = 4 atoms/unit cell, and V C = 16 R 3 2 (Equation 4.6). Now, r I= nA r V C N A = nA Ir (16R3 2)N A And solving for R from the above expression yields R = n A Ir 1 6 per mole, or cal/mol, then the product of Boltzmann’s constant and Avogadro’s constant is to be used in order to consider single atoms . 7 • We can get Q from ρ = 8.4 g/cm3 ACu = 63.5g/mol QV = 0.9eV/atom NA = 6.02 x 1023 atoms/mole 8.62 x 10-5 eV/atom-K 0.9eV/atom 1273K Macroscopically, the ideal gas law states that, for an ideal gas, the product of pressure p and volume V is proportional to the product of amount of substance n (in moles) and absolute temperature T: =, where R is the molar gas constant (8.314 462 618 153 24 J⋅K −1 ⋅mol −1).
