What is meant by 1 mole?
A mole is the amount (10) of material containing 6.02214 × 1023 particles. 1 mol = 6.02214 × 1023 particles. This number is also called Avogadro’s number… …
How do I calculate moles?
So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.
