In an organic chemistry laboratory, a student performs a reaction where compound M (molecular weight = 180 g/mol) is converted to compound N (molecular weight = 162 g/mol) in the presence of a dehydrating agent. The reaction yields N with 90% theoretical yield. If the student starts with 36 grams of M, how many grams of water (HO) are produced in the reaction? A. 3.6 g B. 7.2 g C. 1.8 g D. 18.0 g
