Hello!
First, we need to determine the pKa of the base. It can be found applying the following equation:
Now, we can apply the
Henderson-Hasselbach's equation in the following way:
![pH=pKa+log( \frac{[CH_3NH_2]}{[CH_3NH_3Cl]} )=10,65+log( \frac{0,18M}{0,73M} )=10,04](https://tex.z-dn.net/?f=pH%3DpKa%2Blog%28%20%5Cfrac%7B%5BCH_3NH_2%5D%7D%7B%5BCH_3NH_3Cl%5D%7D%20%29%3D10%2C65%2Blog%28%20%5Cfrac%7B0%2C18M%7D%7B0%2C73M%7D%20%29%3D10%2C04)
So,
the pH of this buffer solution is 10,04Have a nice day!
The position of a given element in the periodic table depends on the atomic number. Further the atomic number is equal to the number of protons and the number of electrons of the particular element.
Also for the considered element, depending on the atomic number, the placement in the periodic table will create groups (columns) and periods (rows).
As a example we will take two atoms carbon (C) and nitrogen (N):
carbon (C) - has a atomic number of 6, it contains 6 protons and 6 electrons, and you find this element in the group 14 and period 2 in the periodic table
nitrogen (N) - has a atomic number of 7, it contains 7 protons and 7 electrons, and you find this element in the group 15 and period 2 in the periodic table
Kingdom Monera, organisms in this Kingdom are prokaryotes, they don't have a nuclear envelope, thus they have a nucleoid.
Answer:
773.51495 grams
Explanation:
1 moles KBr to grams = 119.0023 grams
6.5*119.0023 = 773.51495 grams
