The mass of NaCN needs to be determined.
The dissociation reaction of a weak acid is represented as follows:
The expression for the acid dissociation constant will be as follows:
Here, is concentration of hydrogen ion, is concentration of conjugate base and is the concentration of weak acid.
The molarity of solution is defined as number of moles of solute in 1 L of the solution:
From number of moles, mass can be calculated as follows:
Here, M is molar mass.
