<u>Given:</u>
% Al = 35.94
% S = 64.06
<u>To determine:</u>
Empirical formula of a compound with the above composition
<u>Explanation:</u>
Atomic wt of Al = 27 g/mol
Atomic wt of S = 32 g/mol
Based on the given data, for 100 g of the compound: Mass of Al = 35.94 g and mass of S = 64.06 g
# moles of Al = 35.94/27 = 1.331
# moles of S = 64.06/32 = 2.002
Divide by the smallest # moles:
Al = 1.331/1.331 = 1
S = 2.002/1,331 = 1.5 ≅ 2
Empirical formula = AlS₂
Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.
<h3>What are metals?</h3>
In engineering, metals are characterized to have electrical conductivity and other properties (e.g., ductility, reflectivity, etc).
For example, Lithium can be defined as soft metal (alkali metal) that is suitable to store electrical energy.
In conclusion, Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.
