Whoops made a mistake i subtracted 536.25 by 455.8125 and got 80.4372

Thank you Ms.Sue :) can you help me with B?

I got C10 H20 O but that makes the molar mass 156, not 146 :( am i doing something wrong?

sorry, i made a typo, the question says that the compound has a molar mass of 146 g/mol

184

which equations did you use for this problem?
