Question

how calculate the molecular mass of CaSO4​

Answer 1

Answer:

add mass of all elements

Ca + S + o4

40 +32 + 64

136 apx..

Answer 2

The molecular mass of $CaSO_{4}$ can be calculated by adding the atomic mass of each atom of the compound.

• First separate all the atoms of the compound $CaSO_{4}$ to calculate the molecular mass.

• After separating, add the atomic masses of all the atoms of $CaSO_{4}$.
• Calcium has an atomic mass = 40.08
• Oxygen has an atomic mass = 16
• Sulphur has an atomic mass = 32.06
• Now, by adding the atomic masses of all the atoms

       = 40.08 + 32.06 + 16 × 4 = 136.14

• As the S.I unit of the molecular mass is g/mol
• So, $CaSO_{4}$ has a molecular ,mass of 136.14 g/mol.
