Please help me with chemistry homework This requires the ideal gas laws to solve. Students at a high school in Brekenridge, CO carry out a similar procedure with a larger eudiometer containing 943.5mL of hydrogen gas with known mass of 0.06g at 22 degrees Celsius. Calculate the atmospheric pressure or atm where they live?* Assume the water level inside and outside of the eudiometer are the same just as we assumed in the lab.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
