Final answer:
To calculate the molar heat of solution of KCN, we can use the equation Q = mcΔT and rearrange it to solve for AHsoln.
Step-by-step explanation:
The molar heat of solution of KCN can be calculated using the equation:
Q = mcΔT
Where:
Q is the heat gained by the water,
m is the mass of water, and
c is the specific heat capacity of water
ΔT is the change in temperature of the water.
We can rearrange the equation to solve for Q:
Q = AHsoln x n
Where:
AHsoln is the molar heat of solution of KCN, and
n is the number of moles of KCN.
We can calculate n using the molar mass of KCN:
n = mass / molar mass
Substituting the given values into the equations, we can calculate the molar heat of solution of KCN.
