It means that different compounds composed of the same elements have their own unique proportion of those elements. For example, both water (H2O) and hydrogen peroxide (H2O2) are composed of hydrogen and oxygen. However, the proportion of hydrogen to oxygen in water is 2 to 1, and the proportion of hydrogen to oxygen in hydrogen peroxide is 1 to 1.

What is the other name of law of constant of proportion?
There are several names: on of which is Proust's law.
Who scientist verified law of constant proportion?
Joseph Proust.
What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
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.
The principle that two stimuli must differ by a constant proportion for their difference to be perceived is known as?
Weber's Law"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."
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.

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.
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 does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
How does law of constant proportion applies in sea water?
The law of constant proportion, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass. In seawater, this law applies to the dissolved salts, primarily sodium chloride, which consistently makes up about 3.5% of seawater by mass. Regardless of where seawater is sampled, the proportion of these dissolved salts remains relatively constant, demonstrating that the chemical composition of seawater is uniform despite variations in other components. This consistency is crucial for marine life and oceanic processes.
