27*9=243 if one mole is equal to 27 grams times that by 9
243 g are in 9.0 moles of aluminium if one mole of aluminium atoms has a mass of 27 grams.
What are moles?
A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
One mole of aluminium atoms has a mass of 27 grams.
