What element has 7.767 x 1017 atoms in 6.57 x 10-5 g of material? Carbon, vanadium, Calcium, Chromium, Strontium
The element is Vanadium.
No. of moles = Wt of compound / Molecular wt of Vanadium = 6.57 x 10-5 / 50.94
= 0.1290 x 10-5 moles
No . of atoms = Moles x Avogadros number
= 0.1290 x 10-5 x 6.022 x 1023
= 7.768 x 1017 atoms
