Calculate the Molecular Mass of the CUSO4 . 5h2o

Answer:

Hydrogen has an atomic mass of 1u. Hydrogen is made up of four atoms. Oxygen has an atomic mass of 16u and sulphur has an atomic mass of 32u and copper has an atomic mass of 64u. There is just one carbon atom in the universe. As a result, the molecular mass of  CuSO₄. 5H₂O is 250 u  or 250 g/mol.

The molecular mass (m) of a molecule is measured in Daltons (Da or u). Because various isotopes of an element are present in distinct molecules of the same substance, their molecular weights might vary.

To determine the molar mass, we must first comprehend the procedure for calculating the molar mass of any compound, after which we will proceed with the supplied substance using this procedure. To calculate the molar mass of a specific substance, we will utilise the atomic masses of the constituent elements from the periodic table.

CuSO₄. 5H₂O  is the given chemical.

To determine molecular mass, we’ll first go through the steps below.

• Find out what the molecule’s molecular formula is.
• Determine the atomic mass of each element in the molecule using the periodic table.
• Multiply the atomic mass of each element in the molecule by the number of its atoms. The subscript following the element symbol in the molecular formula represents this number.
• For each atom in the molecule, add these values together.

The total will be the compound’s molecular mass.

To get the molecular mass of  CuSO₄. 5H₂O, we must first determine the atomic masses of copper(Cu), sulphur(S), oxygen(O) and hydrogen (H).

Atomic mass of H – 1 u

Atomic mass of O = 16u

Atomic mass of Cu = 64 u

Atomic mass of S = 32 u

Multiply each atom’s atomic mass by the number of atoms in the compound.

CuSO₄. 5H₂O molecular mass:

= 64u + 32u + (16 4)u + 5( 1 2)u + 16u

= 96u + 64u + 5(18u)

= (96 + 64 + 90)u

= 250 u

As a result,  CuSO₄. 5H₂O has a molar mass of 250 g/mol.
