Question

What is the Δh, in kj/mol, for the dissolution of mgso₄ in water?

A) 5.36
B) 10.72
C) 15.36
D) The Δh cannot be determined from the information given

Answer 1

The ΔH for the dissolution of MgSO4 cannot be determined as the provided information is about KOH, not MgSO4. To calculate ΔHsoln, specific experimental data for MgSO4 would be required.

Step-by-step explanation:

The ΔH for the dissolution of MgSO4 cannot be directly determined from the given information because the data provided pertains to the dissolution of KOH in water, not MgSO4. The ΔHsoln (enthalpy of solution) represents the heat change when one mole of a substance dissolves in a solvent. In the given example regarding KOH, the experiment revealed that the dissolution process released energy, indicating an exothermic reaction with a negative ΔH value. To calculate ΔHsoln for a different substance such as MgSO4, an experiment with specific measurements for that substance would be required. From the information provided, we are unable to deduce the ΔH for the dissolution of MgSO4 in water.
