- What do they mean by: when 1.010 g of zinc vapor is burned in air, 1.257 g of the oxide is produced ?
- Q: I mean what are the formulas of zinc vapor, and oxide?because I don’t really get it. They’re asking for the empirical formula of the oxide, but what is the chemical formula of the oxide?
- A: 1.010 g Zn = 1.010g / 65.38 g/mole = 0.01545 molesmass of oxygen in zinc oxide = 1.257 – 1.010 = 0.247 gatomic weight of O = 160.247 g / 16 g/mole = 0.01544 moles oxygen atomsZn and oxygen combine 0.01545 moles : 0.01544 moles ratio or 1 to 1Therefore the empirical formula is ZnO2Zn + O2 –> 2 ZnO

- Conditions to use Scherrer Equation / Formula to calculate Zinc Oxide pellet particle size after XRD?
- Q: Help! I made zinc oxide pellets and performed powder diffraction performed on them. Basically, we first cold pressed the zinc oxide powder to form a pellet and then annealed it. Then, we did powder diffraction on this sample (for whatever reasons, don’t ask!). All that I have from this is the interplanar spacing d for the different hkl planes, but I must expand this. Question: Can I use the Scherrer formula to calculate the particle size? For what range of particle sizes is it applicable? Would my Zinc Oxide pellet fall into that range?edit – IF you have any other methods in your mind, I would really appreciate your suggestions on other calculations that can be performed besides the lame D spacing and the scherrer formua
- A: From the way you’ve written your question, I get the feeling that you don’t know that there is a difference between the Bragg equation and the Scherrer formula. The Bragg equation, 2dsinθ = nλ, (λ = wavelength) gives you d-spacings but gives you no information about particle sizes. The Scherrer formula is⁽¹⁾t = Kλ/(B cosθ)”where t is the averaged dimension of crystallites; K is the Scherrer constant, somewhat arbitrary value that falls in the range 0.87-1.0 (it is usually assumed to be 1) … and B is the integral breadth of a reflection (in radians 2θ) located at 2θ” The Scherrer formula is only applicable if the particle size is ~ 200 nm or less – it makes use of the line width due to the limited distance range over which constructive interference of the diffracted X-ray occurs. In other words, the particle size information is is in the line broadening, not in the line positions that are used to determine the d-spacings. (See the link.⁽¹⁾)I don’t know if your ZnO pellet would fall into that range because there is no way for me to know the source of your original ZnO.
