What is the molecular mass of Na2SO4?
Step1. Molecular mass
Step2. The formula for molecular mass of Na2SO4
The molecular mass of Na2SO4 =(2×AtomicmassofNa+AtomicmassofS+4×AtomicmassofO)
Step3.Calculation of molecular mass of Na2SO4
The molecular mass ofNa2SO4 =2×22.99+32.06+4×16.00u
=45.98+32.06+64u
=142.04u
Hence, the molecular mass of Na2SO4 is 142.04u.
