Answer: The pH of an aqueous solution of .25M acetic acid is 2.7
Explanation:
cM 0 0
So dissociation constant will be:
Give c= 0.25 M and = ?
Putting in the values we get:
Also
Thus pH is 2.7
Answer:
d) carbon dioxide and water
The elements Carbon, Hydrogen, and Oxygen are all part of Non-Metals.
Hope This Helps! :)
Ah, this is actually a fairly simple chemistry question.
Recall that at STP, one mole is equivalent to 22.4 L. Knowing this, all you have to do is divide 500 L by 22.4 L to find the number of moles:
500/22.4 = 22.3 mol
