Transcribed Image Text: Arenes are a special type of compound consisting of only carbon and hydrogen. If 5.500 g of a specific arene with a molar mass of approximately 155 g/mol yields 18.835 g of CO2 upon combustion in a purely oxygen atmosphere, determine the a) empirical, and b) molecular formulas, for the compound.

CO is carbon monoxide, and is composed of a single atom of each carbon (C) and oxygen (O). Thus, to calculate the molar mass of CO we must know the atomic masses of carbon and oxygen. Atomic mass of carbon = 12.01 amu. Atomic mass of oxygen = 16 amu. Atomic mass of CO = atomic mass of carbon + atomic mass of oxygen = 12.01 + 16 = 28.01 amu

Compound X has a molar mass of 134.12·gmol−1 and the following composition: element mass % carbon 44.77% hydrogen 7.52% oxygen 47.72% Write the molecular formula of X . arrow_forward An unknown compound that is composed of C, H and O atoms was submitted to a lab for determination of formula.

Use percent composition and molar mass to determine molecular formula. Analysis of a compound of carbon, hydrogen and oxygen showed that it is 52.13% C and 13.15% H, with O accounting for the remainder. In a separate experiment, the molar mass of the compound was found to be 46.08 g/mol. Determine the molecular formula of the compound.
