Answer:
Explanation:
Given data:
Mass of aluminium = 95.0 g
Moles of Al = ?
Solution:
Number of moles = mass/ molar mass
Molar mass of aluminium = 27 g/mol
Number of moles = 95.0 g / 27 g/mol
Number of moles = 3.52 mol
Given data:
Moles of FeCl₂ = 2.10 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1 mole = 6.022 × 10²³ molecules
2.10 moles × 6.022 × 10²³ molecules / 1 mol
12.65 × 10²³ molecules of FeCl₂
