The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.
This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.

What is the rule of constant proportions?
The law of constant proportions, also called Proust's law, states that the elements in a compound are all present in a fixed proportion by weight, regardless of how the compound is prepared.
Why is the law of constant composition important to chemistry?
It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.
What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
What in an expression of Dalton's law constant?
Dalton's law of constant proportion states that any sample of a chemical compound will have its constituent elements appearing in the same proportion by mass. Thus 8/9 of the mass of any sample of water will be oxygen and the remaining 1/9 will be hydrogen.
Rules of constant proportion?
Proust's law of constant proportions states that a given chemical compound always contains its component elements in fixed ratio (by weight). The ratio does not depend on its source and method of preparation.
How law of constant proportion applied in experiment empirical formula of a compound?
percentage of mg

Definition: In a direct proportion y = kx, the number k is called the constant of ______.?
proportion
What is a constant variable in a scientific experiment?
That depends on the experiment.
Examples of constant variable?
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
What is the variable that stays the same?
A variable in an experiment that stays the same is a constant.
What is the direct proportion?
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
How do you use constant in a science sentence?
To use constant in a science question, first know that constant in science means a variable that does not change in an experiment. Variables are the different factors that can change in an experiment. For example, a sentence that includes the science word of constant could be: For this experiment, the constant would be... and then you write the constant.
