-A student is determining the enthalpy of solution for ammonium nitrate by adding ammonium nitrate to a calorimeter and measuring the temperature change.

The accepted value is ΔHsol’n = 25.7 kJ/mol.

A student, not paying attention, adds 1.5g of ammonium nitrate instead of 1.0g. When they perform their calculations, they use 1.0g as the mass.

Will their calculation result in an answer that is higher than the accepted value or lower? Explain
