Some students wanted to react a piece of aluminum with sulfuric acid. the students wanted to make sure that they had reliable results and decided to measure their lab temperature and pressure. the LTP were 123004 pascals and 73.141 degrees Fahrenheit. they also made sure that they were going to collect all of the gas that was produced and decided to use a eudiometer to ensure this. if the students added 10.340 g strip of aluminum to the set up which contained 110.00 mL of H2SO4, at 5.500 molar concentration added to 250.00 mL of water, what would be the amount of gas produced and the concentrations of the solution formed? assume a 59.74% yield of the reaction that occurs.
Some other students did the same experiment at their school, but did not know any of the as laws and worked with the molar volume values that related to the conditions at STP. what was the error of their results if they did not use any of the gas laws and the correct LTP? what would be the percent error of their results?
