Question

Benzene is a liquid with molecular formula C6H6.Ethene is a gas with molecular
formula C2H4.Which statement is correct? A 1 mole of benzene and 1 mole of
ethene contain the same number of atoms.B 1 mole of benzene and 1 mole of
ethene both have a volume of 24 dm3 at room temperature and pressure.C Both
benzene and ethene have the same empirical formula.D The number of carbon
atoms in 0.5 moles of ethene is equal to the Avogadro constant.
​

Answer 1

Answer:

Answer: No, one mole of benzene (C6H6) and one mole of ethene (C2H4) will have the same number of molecules (6.02x10^23 benzene molecules and 6.02x10^23 molecules of ethene). However, one molecule of benzene consists of 12 atoms, while one molecule of ethene consists of 6 atoms.
