Answer: 2.60 x 10^23 molecules
50.0 grams x (1 mol/115.79 grams) = 0.431816219 moles
0.431816219 mol x (6.02 x 10^23 molecules/1 mol) = 2.599533638 x 10^23 molecules (final answer is rounded)
Answer: The correct answer is option B i.e., 2.78 mol
Explanation:
Aluminium reacts with iodine to form Aluminium iodide
![$2Al(s)+3I_{2}(s) \to Al_{2}I_{6}(s)$](https://tex.z-dn.net/?f=%242Al%28s%29%2B3I_%7B2%7D%28s%29%20%5Cto%20Al_%7B2%7DI_%7B6%7D%28s%29%24)
From the equation, it is clear that 3 moles of iodine reacts with 2 moles of Aluminium to form Aluminium iodide
We know
For 2 moles of Aluminium, ![$2=\frac{weight}{27}$\\ $weight=2 \times 27=54g$](https://tex.z-dn.net/?f=%242%3D%5Cfrac%7Bweight%7D%7B27%7D%24%5C%5C%20%24weight%3D2%20%5Ctimes%2027%3D54g%24)
3 moles of Iodine reacts with 54 g of Aluminium
? moles of iodine react with 50 g of Aluminium
