Some Chem 16.1 students were tasked to perform the ideal gas experiment with some modifications. Instead of magnesium ribbon, the students were to use 0.029 g of aluminum foil. They prepared the eudiometer by adding 6M HCI and filling it with water to the brim. Once the setup was complete, they performed the experiment. Note that the aluminum was completely consumed in the reaction. From the experiment, it was found that the external pressure was 1.05 atm at 30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The water level inside the eudiometer is 4.15 cm below the surface of the water level outside. Given these measurements and the following constants, answer the proceeding questions. At 30.0°C, Pvapor = 31.8 mmHg • R = 0.08206 L-atm/mol-K = 62.36 L-torr/mol-K • MWAI = 26.98 g/mol A. Find the value of the pressure of dry air (PDA) in torr. B. Give the balanced chemical reaction of the aluminum metal with the acid. C. Find the experimental mass (in grams) of aluminum consumed in the reaction. D. Find the % error of the mass of aluminum from the experiment. ANSWER D ONLY
