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.

Correct
Using the stoichometric coefficients in the chemical equation:
2H₂O(1)→2H₂(g) + O2(g)
you can determine that 2.73x10-4 mol of oxygen gas is produced, which is half the number of moles of
hydrogen gas produced.
Part B
Calculate the magnitude of the current in amperes if the number of moles of hydrogen gas produced is 5.47x10-4 mol
(from part A).
Selenic acid, H2SeO4, is produced from elemental selenium in a two-stage reaction. First the selenium isoxidized to selenous acid by nitric acid. Then the selenous acid is oxidized by potassium permanganate toselenic acid. The equations are:3 Se (s) + 4 HNO3 (l) + H2O (l) → 3 H2SeO3 (aq) + 4 NO (g)8 H2SeO3 (aq) + 2 KMnO4 (aq) → 5 H2SeO4 (aq)+ K2SeO3 (aq)+ 2 MnSeO3 (aq) + 3 H2O (l)What mass of selenic acid (in kg) can be produced from 1.00 kg of Se?Molar masses (g/mol): Se 78.96 H2SeO4 144.97
