Answer:
n = 1.7 moles
Explanation:
Given mass, m = 23.8 grams
Molar mass of Nitrogen = 14 g/mol
Let there is n number of moles. We know that,
No. of moles = given mass/ molar mass
So, there are 1.7 moles in 23.8 grams of Nitrogen.
The question is incomplete, here is the complete question:
Calculate the pH at of a 0.10 M solution of anilinium chloride . Note that aniline
is a weak base with a
of 4.87. Round your answer to 1 decimal place.
<u>Answer:</u> The pH of the solution is 5.1
<u>Explanation:</u>
Anilinium chloride is the salt formed by the combination of a weak base (aniline) and a strong acid (HCl).
To calculate the pH of the solution, we use the equation:
where,
= negative logarithm of weak base which is aniline = 4.87
C = concentration of the salt = 0.10 M
Putting values in above equation, we get:
Hence, the pH of the solution is 5.1
Answer: for the reaction is 3.45
Explanation:
The balanced chemical reaction is:
At eqm. 0.562 atm 0.101 atm 0.332 atm
As we are given that:
The expression of for above equation follows:
Putting values in above equation, we get:
The value of for the reaction is 3.45
