WebApr 12, 2024 · The oxygen content of all atom probe specimens was 1.1 ± 0.1 at.%. Additional oxygen uptake was avoided due to vacuum capillary sealing of the samples before annealing, and the oxygen-rich regions, observed after 5 and 10 h of annealing, are therefore caused by redistribution of oxygen. WebCorrect option is D) Here, diameter, d=3 Ao. ∴r= 2d= 23×10 −10m= 23×10 −8cm =1.5×10 −8cm. Molecular volume of oxygen gas, V= 34πr 3×N. N→ Avogadros number. Actual volume occupied by 1 mol of oxygen gas at STP=22,400 cm 3. ∴V= 34×3.14×(1.5×10 −8) 3×6.023×10 23=8.51cm 3.
