Vedclass · Answer

(B) The postulate of Dalton's atomic theory that led to the law of conservation of mass is: $Atoms$ can neither be created nor destroyed in a chemical reaction.To calculate the molecular mass of water $(H_2O)$:Atomic mass of $H = 1 	ext{ u}$Atomic mass of $O = 16 	ext{ u}$Molecular mass of $H_2O = (2 	imes 	ext{atomic mass of } H) + (1 	imes 	ext{atomic mass of } O)$$= (2 	imes 1) + (1 	imes 16) = 2 + 16 = 18 	ext{ u}$.

State the postulate of Dalton's atomic theory which led to the law of conservation of mass. Calculate the molecular mass of water.
