Explanation:
Given parameters:
Mass of AgNO₃ = 1000mg
Volume of water = 500mL
Unknown:
Molarity of solution = ?
Solution:
The molarity of a solution is the number of moles of a solute dissolved in volume of solvent.
Molarity =
Number of moles of AgNO₃ = ?
Number of moles =
Molar mass of AgNO₃ = 108 + 14 + 3(16) = 170g/mol
convert mass to g;
1000mg = 1g
Number of moles = = 0.00588moles
convert the given volume to dm³;
1000mL = 1dm³;
500mL = 0.5dm³
Now solve;
Molarity = = 0.012moldm⁻³

Explanation:
- When an aqueous solution of a certain acid is prepared it is dissociated is as follows-
⇄
Here HA is a protonic acid such as acetic acid,
- The double arrow signifies that it is an equilibrium process, which means the dissociation and recombination of the acid occur simultaneously.
- The acid dissociation constant can be given by -
=
- The reaction is can also be represented by Bronsted and lowry -
⇄
- Then the dissociation constant will be
=
Here, is the dissociation constant of an acid.
