What is the relationship between relative mass and molar mass?

In summary, relative mass is the comparison of an object or substance's mass to another, and is commonly used in chemistry. It is calculated by dividing the mass of one object by another. Molar mass, on the other hand, is the mass of one mole of a substance and is measured in grams per mole (g/mol). It is determined by adding the atomic masses of each element in a molecule or compound, which can be found on the periodic table. Molar mass is important in chemistry because it allows for easy conversion between moles and grams, making it useful in various calculations and experiments.

Molar mass is the mass of one mole of atoms of the element .

Relative mass is average mass of one atom of that element compared to 1/12 of mass of one carbon-12 atom

I don't understand how they are equal. Can someone explain to me please?

We defined mole in such a way it works.
 

1. What is relative mass?

Relative mass refers to the mass of an object or substance in relation to another object or substance. It is often used in chemistry to compare the mass of atoms and molecules.

2. How is relative mass calculated?

Relative mass is calculated by dividing the mass of one object or substance by the mass of another object or substance. This is typically done using a scale or balance.

3. What is molar mass?

Molar mass is the mass of one mole of a substance. It is measured in grams per mole (g/mol) and is used to express the mass of atoms, molecules, or compounds in a sample.

4. How is molar mass calculated?

Molar mass is calculated by summing the atomic masses of each element in a molecule or compound. The atomic mass can be found on the periodic table of elements.

5. Why is molar mass important in chemistry?

Molar mass is important in chemistry because it allows us to easily convert between the number of moles of a substance and its mass in grams. This is useful in many calculations and experiments.
