Calculate the mass of NH₄ClO₄, molar mass = 117.49 g mol^-1, required to create a temperature change of -1.0 °C in a coffee cup calorimeter containing 115 mL of water. The enthalpy of solution for NH₄ClO₄ is 33.47 kJ mol^-1. The specific heat of water is 4.184 J g^-1 °C^-1, and assume the density of the solution is 1.00 g mL^-1.

The correct answer is A.The mass of NH4ClO4 required can be calculated using the following equation:$$q = m * C * \Delta T$$where:* q is the heat absorbed or released (in joules)* m is the mass of the substance (in grams)* C is the specific heat capacity of the substance (in J/g°C)* ΔT is the change in temperature (in °C)In this case, we have:* q = -1.0 °C * 115 g * 4.184 J/g°C = -480.9 J* C = 33.47 kJ/mol / 117.49 g/mol = 285 J/g* ΔT = -1.0 °CSubstituting these values into the equation, we get:$$-480.9 J = m * 285 J/g * -1.0 °C$$Solving for m, we get:$$m = 1.7 g$$
