Answer:
The answer is
<h3>
</h3>
Explanation:
The Ka of an acid when given the pH and concentration can be found by
<h3>
</h3>
where
c is the concentration of the acid
From the question
pH = 5.82
c = 0.010 M
Substitute the values into the above formula and solve for Ka
We have
<h3>
</h3><h3 /><h3>
</h3><h3 /><h3>
</h3>
Multiply through by - 2
<h3>
</h3>
Find antilog of both sides
We have the final answer as
<h3>
</h3>

5
mL acetic acid
95
mL water
Explanation:
Since
5
%
of the vinegar, by volume, is acetic acid, and we have
100
mL of vinegar, we have
5
mL of vinegar.
Similarly, we have
100
%
−
5
%
=
95
%
being water, so we have
95
mL of water.
Answer:
A. 3 x 10-12
Explanation:
Generally, the parts-per notation is used to represent very small concentration without any specific unit.
Parts per million is notated as 
Parts per billion is notated as 
Parts per trillion is notated as 
Hence, 3 parts per trillion will be written as 3 x
The correct option is A.
