Molecular mass of 128 grams of aluminium atom is as follow:---
●we know that 1 mole is the molecular mass of any substance .
●1 mole of aluminium is equal to molecular mass of Al which is 27 g.
●Mole =given weight /molecular wt
●Given weight=128g
●Molecular mass =27g
●Moles=128/27
●Moles=4.7moles
Hence is 128 grams of aluminium there are 4.7 moles of aluminium.
