The provided balanced equation applies to the reaction that takes place between lithium, hydroxide and sulfuric acid. 2LiOH + H2SO4 --> Li2SO4 + 2H2O. If the reaction begins with 26.7 grams of lithium hydroxide (LiOH) and 164.048 grams of sulfuric acid (H2SO4), how many grams of lithium sulfate (Li2SO4) is produced? Assume 100% yield. Round your answer to the nearest tenth of a gram​

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.
