Answer:
FAS concentration = 1.61*10^-4M
Explanation:
Beer Lambert's law relates the absorbance (A) of a substance to its concentration (c) as:
![A = \epsilon lc----(1)](https://tex.z-dn.net/?f=A%20%3D%20%5Cepsilon%20lc----%281%29)
where ε = molar absorption coefficient
l = path length
A plot of 'A' vs 'c' gives a straight line with slope = εl
In addition absorbance (A) is related to % Transmittance (%T) as:
A = 2-log%T----(2)
For the FAS solution, the corresponding calibration fit is given as:
y = 3678(x) + 0.056
This implies that the slope = εl = 3678
It is given that %T = 25.6%
![A = 2-log(25.6)=0.592](https://tex.z-dn.net/?f=A%20%3D%202-log%2825.6%29%3D0.592)
Based on equation(1):
![c = \frac{A}{\epsilon l}=\frac{0.592}{3678}=1.61*10^{-4}M](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7BA%7D%7B%5Cepsilon%20l%7D%3D%5Cfrac%7B0.592%7D%7B3678%7D%3D1.61%2A10%5E%7B-4%7DM)
It produces nitrogen gas and water

Protons, neutrons, and electrons.
Answer:
Su fórmula molecular es Na Cl y es el producto de la base hidróxido sódico (NaOH) y ácido clorhídrico, H Cl. En general, las sales son compuestos iónicos que forman cristales. Son generalmente solubles en agua, donde se separan los dos iones. Las sales típicas tienen un punto de fusión alto, baja dureza, y baja compresibilidad.
