(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) =
0.3586848223x10^1 which your answer should be 3.59 moles
2,16 x 1024 atoms of lead is equal to 3,58676 moles.
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
2.26*1024
3.4 X 10^24 Pb atoms (1 mole Pb/6.022 X 10^23) = 5.6 moles of lead
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
4.2 X 10^24 atoms of gold / 6.022 X 10^23 atoms per mol) = 7.0 moles of gold
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
