Question

find the molecular mass of mgso4

Answer 1

The molecular mass of Magnesium Sulphate (MgSO₄) can be found in the following steps:

• The molecular mass of any compound or a molecule can be found by adding the weight of all the atoms or ions that are combined chemically.
• The molecular mass of any substance is expressed in Daltons or written as "u".
• Therefore, the molecular mass of Magnesium Sulphate is the sum of the weight of magnesium ions (Mg²⁺) and sulfate ion (SO₄⁻).

     => Molecular mass of Magnesium Sulphate = 1 (Mass of magnesium) + 1  

          (Mass of sulfur) + 4 (Mass of oxygen)

    => Molecular mass of MgSO₄ = 24.305 u + 32.065 u + 4 (15.999) u

    => Molecular mass of MgSO₄ = 56.37 u + 63.996 u

    => Molecular mass of MgSO₄ = 120.366 Daltons

• Hence, the molecular mass of Magnesium Sulphate (MgSO₄) is 120.366 daltons.

Answer 2

Answer:

Atomic mass of magnesium (Mg) = 24

atomic mass of sulphur (S) = 32

atomic mass of 4 atoms of oxygen (O 4 ) = 16x4 = 64

molecular mass = 24 + 32 + 64 = 120
