Hi the answer is 1/6, because 1/6 of 3,600 is 600, so it's 1/6. Have a great day!
Answer:
- <em>(B.) The pH of a buffer solution is determined by the ratio of the concentration of conjugate base to the concentration of strong acid.</em>
- <em>(C.) A buffer is generally made up of a weak acid and its conjugate base. </em>
- <em>(D.) The pH of a buffer solution does not change significantly when any amount of a strong acid is added.</em>
Explanation:
A buffer is solution which resists change in pH upon addition of either acids or bases.
The pH of a buffer is calculated by the ratio of the concentration of base to concentration of acid. The weak acid and conjugate base have a Ka similar to the pH desired.
<u>Answer:</u> The total pressure inside the container is 77.9 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the total pressure inside the container, we use the law given by Dalton, which is:

We are given:
Vapor pressure of oxygen gas,
= 40.9 kPa
Vapor pressure of nitrogen gas,
= 23.3 kPa
Vapor pressure of argon,
= 13.7 kPa
Putting values in above equation, we get:

Hence, the total pressure inside the container is 77.9 kPa
