1.3 x 10²⁴molecules
Explanation:
Given parameters:
Mass of Mn(SO₄)₂ = 542.32g
Unknown:
Number of molecules in the compound = ?
Solution:
The number of moles is the unit used to express the number of particles in a substance.
A mole contains 6.02 x 10²³ molecules
Number of moles =
Molar mass Mn(SO₄)₂ = 55 + 2(32 + 4(16)) = 247g/mol
Number of moles = = 2.2moles
1 mole = 6.02 x 10²³ molecules
2.2 moles = 2.2 x 6.02 x 10²³ molecules = 1.3 x 10²⁴molecules
