You are asked to identify compound X (a white, crystalline solid), which was extracted from a plant seized by customs inspectors. An elemental analysis of X shows that the mass percentage composition of the compound is 26.86% C and 2.239% H, with the remainder being oxygen. A mass spectrum of X yields a molar mass of 90.0 g/mol. Write the empirical formula of X.
