Can anyone help me get a better idea of the molar mass concept and please don't give me a copy paste answer i have checked many websites already ?

Molar mass, which you have probably already read, represents the weight of one mole of a material (or compound).

Think of it like this. One mole of any element has exactly #6.022 * 10^(23)# atoms, also known as Avogadro's number. However, the weight of a single atom varies across the periodic table because of the increase in atomic number, i.e the number of protons an atom has in its nucleus.

This is why the molar masses of heavier elements are bigger than the ones of lighter elements. You still have the same amount of atoms present, #6.022 * 10^(23)#, but now each individual atom weighs more, which implies that 1 mole of those atoms will weigh more.

Assuming you have a basketball team, for example, five players will represent one mole of players. It goes without saying that the "molar mass" of an NBA team and an elementary school team will differ.

Due to the disparity in weight between each member of the NBA team, five elementary school players will have a lower "molar mass" than the team.

This is what molar mass essentially means - how much a "team" of atoms weighs for a particular element. The same idea is true for compounds - the molar mass of water, for instance, expresses how much #6.022 * 10^(-23)# molecules of water weigh.

undefined Indeed, molar mass is the mass of one mole of a substance, usually given in grams per mole (g/mol). It is computed by adding up the atomic masses of all the atoms in the substance's chemical formula. In other words, molar mass is the mass of the constituent particles of a substance on a macroscopic scale, enabling chemists to relate mass to the quantity of particles present. For instance, molar mass of water (H2O) is approximately 18.015 g/mol, meaning that one mole of water molecules has a mass of roughly 18.015 grams. Molar mass is a crucial concept in chemistry because it is used in a variety of calculations, such as figuring out how much substance is required for a reaction and converting between mass and moles.

undefined Of course. Molar mass refers to the mass of one mole of a substance, expressed in grams per mole (g/mol). It is calculated by adding up the atomic masses of all the atoms present in a molecule or formula unit. For elements, the molar mass is equal to the atomic mass listed on the periodic table. For compounds, the molar mass is determined by summing the atomic masses of each element present in the compound, multiplied by the number of atoms of that element in the formula. Molar mass is a crucial concept in chemistry, as it is used in various calculations involving moles, such as determining the amount of substance present in a given mass or volume, or in stoichiometry calculations. Understanding molar mass allows chemists to accurately quantify substances and predict their behavior in chemical reactions.
