The vapor pressure of dichloromethane, CH2Cl2, at 0 oC is 134 mmHg. The normal boiling point of dichloromethane is 40. oC. Calculate its molar heat of vaporization. Enter your answer numerically, to three significant figures and in terms of kJ/mol.

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
