3. Calculate the amount of HCl produced.
The total amount of HCl produced with a 90.0% yield is:
Answer: Option (5) is the correct answer.
Explanation:
It is known that more is the number of carbon atoms linearly present in a compound more will be its boiling point. This is because then more number of intermolecular forces are present within the atoms of a compound.
Hence, lesser is the number of carbon atoms present less will be the intermolecular forces present in it. Therefore, more readily the compound will evaporate into the atmosphere.
Thus, we can conclude that given compounds are ranked in increasing rate of evaporation as follows.

Freezing point is the temperature at which a substance undergoes a phase transition from liquid to solid state. Water converts from liquid state to solid ice at a temperature of .
Mass is the amount of matter contained in a substance. The SI unit of mass is kilogram. 1 kilogram is equal to 1000 g. One kilogram is defined as the mass of one cubic decimeter of water at the freezing point of water.
