Vedclass · Answer

(D) The molar mass of $CO_2 = 44 \ g/mol$. $44 \ g$ of $CO_2$ contains $12 \ g$ of carbon. $1.32 \ g$ of $CO_2$ contains $(1.32 	imes 12) / 44 = 0.36 \ g$ of carbon. The molar mass of $H_2O = 18 \ g/mol$. $18 \ g$ of $H_2O$ contains $2 \ g$ of hydrogen. $2.7 \ g$ of $H_2O$ contains $(2.7 	imes 2) / 18 = 0.30 \ g$ of hydrogen. Total mass of carbon and hydrogen after combustion $= 0.36 \ g + 0.30 \ g = 0.66 \ g$. Since the total mass of the elements before and after the reaction remains the same,it follows the Law of Conservation of Mass.

Complete combustion of $0.66 \ g$ of a hydrocarbon gives $1.32 \ g$ of $CO_2$ and $2.7 \ g$ of water. The results of the given data follow the law of ...
