Question

by Na =N exp(-Q/kT) How can I enter exp in calculator or how can I solve this exp Boltzmann constant, k = 8.62 x 10-5 ev/atom·K, Avogadro's constant, NAv. 6.022 x 1023 mol-l Calculate the equilibrium number of vacancies per cubic meter in gold (Au) at 25°C. For gold, the energy for vacancy the theoretical density for gold are 196.9 g/mold19.32 g/cm' (at 25 C), respectively. n is 0.98 eV/atom. Furthermore, the atomic mass and TD 2. a-iron, which is one of the polymorphic forms of iron (Fe), has a BCC crystal structure at 25°C. Determine the number of vacancies per cm needed for this crystal to have a density of 7.86 g/cm2 at 25°C. The atomic mass of iron is 55.85 g/mol and the lattice parameter of a-iron is 0.286 nm. old (Au) forms a substitutional solid solution with silver (Ag) a) Compute the weight percent of gold that must be added to silver to yield an alloy that contains 5.50 x 1021 gold atoms per cubic centimeter of alloy. The densities of pure gold and pure silver at 25°C are 19.32 g/cm3 and 10.49 g/cm', respectively. The atomic masses of gold and silver are 196.9 g/mol and 107.8 g/mol, respectively. b) What type of positions, lattice or interstitial, are occupied by gold atoms in the solid solution? Go

Explanation / Answer

Hi i would like to prefer to use online calculator always at

https://www.google.co.in/search?q=root+calculator&ie=utf-8&oe=utf-8&gws_rd=cr&ei=8PoJV-e8HuPtmQXazbP4Dg

1. click on e button

2. click on Xy button

3. enter the value to be calculated

4. click on = button

5. you will get the required value.

OR

1. click exp button on your calculator, it shows as e

2. click on Yx

3. enter the value required to calculate

4. click on ) button

5. click on = button to get final answer ya.

sometimes on one calculator, it does e^x, and the other calculator just does "e". So you had to enter it as e y^x.

Cross-check with known values before performing calculations (This process is known as calibration in science)

check e^0.5 = 1.6487212707 if you get this value you are going in right direction.

I can solve the equation for you, but everytime you depends on me for next question requires this exp function, hence i decided to give idea on how to do it yourself (DIY).

Thank You So Much! Please Rate this answer as you wish.
