Question

When a 3.00 g sample of kscn is dissolved in water in a calorimeter that has a total heat capacity of 2.20 kJ/K, the temperature decreases by 0.340 K. Calculate the molar heat solution of kscn.

Answer 1

To calculate the molar heat of solution of KSCN, you need to find the number of moles of KSCN dissolved in water.

Step-by-step explanation:

The molar heat of solution, AHsoln, can be calculated using the formula:

AHsoln = q / (n * m)

Where q is the heat change in the calorimeter, n is the number of moles of solute, and m is the mass of the solute. In this case, we have the mass of the sample and the temperature change, but we need the number of moles of KSCN. We can calculate the number of moles using the molar mass of KSCN:

molar mass = mass / moles

Once we have the number of moles, we can calculate the molar heat of solution using the formula mentioned above.
