Dalton's atomic theory led to a prediction that must be true if the theory is correct: when two elements combine to form a compound,the masses in which they combine is constant..What is the name of this Law that followed from Dalton's atomic theory?
A)The Law of Weight Ratios
B)The Law of Multiple Proportions
C)The Law of Definite Composition
D)The Law of Conservation of Weight
E)The Law of Conservation of Mass

The Law of Definite Composition states that a given compound always contains exactly the same proportion of elements by mass. This law follows from Dalton's atomic theory, which proposed that elements combine in fixed ratios to form compounds, and that the ratio is determined by the number and relative masses of the atoms involved. The Law of Definite Composition is also known as the Law of Constant Composition.
