Question

Calculate the number of aluminium atoms in 0.056g of

aluminium oxide(AL2O3) (AL=27 O=16)​

Answer 1

Answer:

no idea dear..........

Answer 2

Explanation:

mol mass of Al2O3=102 g

So, No. of moles of Al atoms in 0.056g = 0.056/102=0.0005

so, No of Al atoms = 0.0005× Na

where Na= Avagadro Number
