The molecular weight of elemental aluminum is 13 grams, which contains 6.02 x 10^23 atoms. Therefore 1 gram of elemental aluminum contains [(6.02 x 10^23) divided by 13] atoms.
Notice that the value 12.01 grams of natural carbon is the same as the atomic mass value (12.01 amu). It also tells us that 26.98 grams of aluminum contains exactly 6.022 x 1023 atoms of aluminum.
Additionally, how many atoms are present in 9g of Aluminium? So 9.0 gram of Al will contain=9/26.998= 0.333 moles of Al. No. Of atoms of Al in 9 gram = 0.333× Avogadro no. =0.333×6.022×10^23=2.005×10^23 atoms.
Consequently, how many atoms are in an Aluminium can?
This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element. This means that if you know how many moles of aluminium you have in 4.55 g , you can use Avogadros number to find the number of atoms.
What is the mass of 6.02 x10 23 atoms of aluminum?
David G. One mole of aluminum atoms has a mass of 26.98 grams, and contains 6.02×1023 atoms. Dividing 26.986.02×1023 yields a mass of 4.48×10−23 g for one aluminum atom.
