Mole Concept and Molar Mass
A molecule is the smallest group of atoms that retains all the chemical properties of a substance. Molecules are formed when atoms bond together, and they can combine with other molecules to form larger molecules. For example, consider a water molecule (H2O), which is made up of two hydrogen atoms and one oxygen atom.
Molar Mass is a measure of the mass of a mole of a substance. It is equal to the total mass of all the atoms in a mole of that substance. For instance, the molar mass of water is 18.015 g/mol, which means that a mole of water contains 18.015 grams of hydrogen and 1.008 grams of oxygen.
By understanding the concept of molecules and molar mass, chemists can analyze and compare substances, predict their properties, and develop new materials
