If the reaction begins with 26.7 grams of lithium hydroxide and 164.08 grams of sulfuric acid how many grams of lithium sulfate is produced? Assume 100% yield round your answer to the nearest tenth of a gram

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
