The number of carbon atoms in a molecule of compound is .
Answer: 3
Solution
At STP one mole of a gas occupies mL, so
and the molar mass of A is
Ozonolysis followed by hydrolysis gives only aldehydes, so A carries a carbon-carbon double bond with a hydrogen atom on each of the doubly bonded carbons. A monochloroalkene has the formula , of molar mass . Setting gives , and the compound is allyl chloride , whose ozonolysis gives methanal and chloroethanal, both aldehydes. A molecule of A contains carbon atoms.
