write a summary of each of the techniques for measuring vacancyconcentrations, noted therein. (1) Measurements of the quenched-in residual electricalresistivity of aluminium rapidly cooled from temperatures be-low about 800 K with initial quenching rates of 2 × 106 K s−1give the enthalpy of formation of monovacancies H F1V =(0.65 ± 0.01) eV.(2) Comparison of the quenching data with high-temperature differential-dilatometry data gives the monova-cancy formation entropy SF1V = (0.76 ± 0.4)kB (kB =Boltzmann’s constant) and the low-temperature resistivity perunit concentration of vacancies ρ1V = (1.9 ± 0.1) μm.(3) The binding enthalpy of divacancies in Al is H B2V =(0.17 5 ± 0.02 5) eV. This is in agreement with earlier ex-perimental determinations by Doyama and Koehler 48) and byLevy et al. 49, 50) but in marked contrast to the claim of Carlinget al., 23) based on computations with the generalized gradi-ent approximation, that in Al H B2V is zero or even negativeand therefore the…

In an analysis of chromium in steel containing 1.76% Cr. 0.5000 g of that steel is weighed and dissolved in acid, whereupon the Cr is oxidized to Cr2O72- (dichromate), and blunt to a volume of 250 mL. A 10 mL aliquot of this solution is diluted with water and acid to a final volume of 100 mL. The resulting solution shows a transmittance of 41.7% in a 1 cm pathlength cell. When a 0.7500 g sample of unknown steel is dissolved in acid, oxidized, and diluted to 250 mL, the resulting solution exhibits a transmittance of 61.3% under identical experimental conditions. What is the percentage of Cr in the steel?
