For your research project, you need to use isotopic labels. For this you buy chlorine gas (Cl2) that uses exclusive 37Cl atoms. What is the molar mass of the gas you purchased.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

gas you purchased.
The basic constituent of a substance is known as an atom that has a nucleus consisting of protons and neutrons. The electrons surround the nucleus with a negative charge. The combination of atoms produces a molecule with a definite composition.
The moles of the substance are obtained by relating the mass and the molar mass. Mathematically, it is expressed as follows.
If the molar mass of a substance is increased with a constant mass, then the number of moles gets decreased.
