A chemistry student is given a sample of an unknown salt consisting of a mixture of two compounds. The student is asked to determine the percentage composition of each compound in the salt using mass balance calculations. The total mass of the sample is 10 grams, and after performing careful analysis, the student obtains the following data: One compound has a molar mass of 80 g/mol and comprises 60% of the total mass of the salt. The other compound has a molar mass of 120 g/mol and comprises 40% of the total mass of the salt. What are the percentage compositions of each compound in the salt?

Calculate the enthalpy change for the precipitation reaction between 50.0 mL of 0.150 M silver nitrate solution and excess sodium chloride solution if the temperature change was measured to be -5.47°C. The molar mass of AgNO3 is 169.87 g/mol, and the density of the silver nitrate solution is 1.05 g/mL. The reaction is as follows: AgNO3(aq) + NaCl(aq) -> AgCl(s) + NaNO3(aq).
