In order to change celcius to kelvin always add 73 to it leaving you with -195.93
Answer:
What is the question? I don't understand what you are trying to say.
Answer:
1.52 M
Explanation:
Molarity of a solution is calculated as follows:
Molarity = number of moles (n) ÷ volume (V)
Based on the information given in this question,
Volume of soda (V) = 9.13 L
number of moles = 13.83 mol
Molarity = 13.83 ÷ 9.13
Molarity = 1.52 M
Answer:- The pH of the buffer solution will be 4.04 .
Solution:- Sodium acetate added to acetic acid makes a buffer solution and the pH of buffer solution is easily calculated by using Handerson equation:

We are adding 25.00 mL of each, so the total volume of the buffer solution will be 50.00 mL.
We can calculate the concentration of base which is sodium acetate and acid by using dilution equation:


for base:


Similarly, for acid:


pKa is calculated from given Ka value as:


pKa = 4.74
Let's plug in the values in Handerson equation:

pH = 4.74 - 0.70
pH = 4.04
They use models when they are trying to find stuff in the ground like fossils so they match them up so they can find if it’s the same or not please mark brainliest must appreciated !
