One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon - 12(6. 023×1023).
The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula.
Moles are units used to measure substance amount. Chemistry (Single Science) Atomic structure.
To solve ,
number of moles is equals to the mass in grams divided by RFM
