______________________________

✔️Formula mass of a substance is expressed as the sum of atomic masses of constituent atoms in an ionic compound.

✔️ $K_{2}CO_{3}$ is the formula of Potassium carbonate.

✔️Formula unit mass of Potassium Carbonate:-

2 × 39 + 12 + 3 × 16

78 + 12 + 48

126 + 12

138

✔️So, the formula unit mass of Potassium Carbonate will be 138u.

vaibhavsethia71691: Sry yr but the ans is wrong

Suryavardhan1: It is right answer

vaibhavsethia71691: The compound is K2SO3 which means that two atoms of potassium,one of carbon and three of oxygen= 39*2+12+16*3=138

vaibhavsethia71691: sry sry......... i was wrong..... i wrote sulphur instead of carbon.... SRY bro

Suryavardhan1: Extremely, I wrote 2 Insted of 3

Suryavardhan1: Wait, I will edit it soon

vaibhavsethia71691: we both made mistakes

K2CO3

Atomic mass of potassium(k)=39

-----^---- carbon(c)=12

---------^------oxygen(o)=16

=39×2+12+16×3

=78+12+48

=90+48

=138
