Is mass the same as molar mass?
No. Mass is the mass (weight in common terms) of an individual object, whether it be an atom, molecule, or a dinner plate (or a person). Molar mass is the mass of 1 mol of material.
Thank you.
No, mass and molar mass are not the same. Mass refers to the amount of matter in an object or substance, often measured in units like grams or kilograms. On the other hand, molar mass is a specific type of mass that is used in chemistry to describe the mass of one mole of a substance.
To calculate the molar mass of a substance, you need to know the atomic masses of all the elements present in its chemical formula. The atomic masses of elements are listed on the periodic table.
For example, let's take water (H2O). The molar mass of water can be calculated by adding up the atomic masses of two hydrogen atoms (H) and one oxygen atom (O). The atomic mass of hydrogen is approximately 1 gram per mole (g/mol), and the atomic mass of oxygen is approximately 16 g/mol. Therefore, the molar mass of water is 18 g/mol.
So, while mass refers to the amount of matter in general, molar mass specifically refers to the mass of one mole of a substance.
