Question

Molar mass formula ..​

Answer 1

Explanation:

Molar mass

M = m / n

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

FROM THE WEB

Molar mass = mass/mole = g/mol

Answer 2

M = m / n

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

Molar mass = mass/mole = g/mol

The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. The mass of one mole of carbon-12 atoms is exactly 12 grams; its molar mass is exactly 12 grams per mole.

Relative molar mass is defined as the smallest mass unit of a compound with one twelfth of the mass of one carbon – 12 atom.

The standard unit for this is g mol−1. However, the SI unit is kg mol−1, which is very rare.

Mole Concept

The amount of atoms present in 12g (0.012 kg) of the 12C isotope is the amount of particles present in 1 mole of the substance. One of the most important facts that should be kept in mind is that the mole of a substance always contains the same number of entities whatever the substance may be.
