The** mass ratio **of potassium and selenium in the given compound is equal to 1 : 2.
What is the mass ratio?
The **mass ratio **also known as the percent composition by mass defines the proportion of a particular compound that consists of the **constituent elements **of that compound.
The** percent composition by mas**s of a constituent element of a compound can be determined by the division of the mass of that element by the molar mass of the compound, followed by its multiplication by 100.
According to the** law of constant proportion**, a pure compound is always made up of the same elements combined together in a fixed proportion by weight.
Given the mass of the potassium (K) in the compound = 39 g
The mass of selenium (Se) in the compound = 78
The mass ratio of K and Se is 39 : 78
The simplest form of the ratio of potassium and selenium is 1 : 2.
