The following information was recorded by a student team working to prepare nickel sulfate. Plan: Prepare NiSO4 by reacting NiO with 6 M H2SO4 The expected product is NiSO4·6H2O. We will filter the crystals from the reaction solution to get the product. NiO + H2SO4 --> NiSO4 + H2O molar mass of NiO: 74.69 g/molmolar mass of NiSO4: 154.75 g/mol molar mass of NiSO4·6H2O: 262.85 g/mol mass of NiO used: 7.5 gvolume of 6M H2SO4 used: 50 mL heated the solution for 30 minutes, cool and filtered the crystals mass of product: 17.4 g Two students calculated percent yield using this data. One student got 66.2% and another got 112%. Based on this information, which of the following statements are true. One or more statements are correct. Group of answer choices The percent yield of 112% was calculated using the molar mass for the hydrated product. The percent yield of 66.2% was calculated using the molar mass for the anhydrous product. Both percent yields are incorrect because…
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.
