On her way out of the base, Rey also found a mysterious unknown acid. After bringing it back to the rebel base, a rebel scientist conducted a titration to test
the acid. In order to test the concentration with titration, we need to make a
basic solution. How many grams of NaOH will we need to make 180 ml of 2.0 M
NaOH? Type your answer with the number and no unit. Round your number to
the nearest tenth.

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.
