Following the general experimental procedure of Experiment 33B, 62 milligrams (mg) of 9-fluorenone (180.20 g/mol) was isolated after purification. This amount of product resulted in a 73% yield for the oxidation reaction. Given these data, what amount of 9-fluorenol (182.22 g/mol), in milligrams (mg), was used for this reaction? Enter your answer as digits only (no units), using the proper number of significant figures.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
