This is how I got to that answer. Since we don't know how many atoms there are in a mole, we use the number 6.02 x 10^-23. Now, just plug in what you have in the equation:
<span>1.75 moles ChCl3 x (6.02 x 10 ^-23) / 1 mole = 1.0535 x 10^-22 atoms. </span>
Protons, it was once organized by atomic mass but organizing by protons turned out to be better
Using the method chromatography
0.040 mol / dm³. (2 sig. fig.)
<h3>Explanation</h3>
in this question acts as a weak base. As seen in the equation in the question, produces rather than when it dissolves in water. The concentration of will likely be more useful than that of for the calculations here.
Finding the value of from pH:
Assume that ,

.
Solve for :
Note that water isn't part of this expression.
The value of Kb is quite small. The change in is nearly negligible once it dissolves. In other words,
.
Also, for each mole of produced, one mole of was also produced. The solution started with a small amount of either species. As a result,
.
