What is the Relative Molecular Mass of sodium sulphate?

 

---------------------------------------------------

 

The Relative Molecular Mass of a compound is

the sum of the masses of all the atoms present in the molecule.

= 화합물의 화학식량, 몰질량

( 참고: 화학식량 https://ywpop.tistory.com/3228 )

 

It is often shortened to RMM.

 

 

Sodium sulphate, Na2SO4RMM

= 2(Na) + (S) + 4(O)

= 2(23) + (32) + 4(16)

= 142
