Answer:
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 x 1023). The mass of one mole of a substance equals its relative molecular mass expressed in grams. Also spelled as mol.
The formula to find the amount of moles of a substance used is: actual mass divided by relative molecular mass.
Therefore,
60/40 = 1.5 moles
