Answered by PᴀʀᴛʜTʀɪᴘᴀᴛʜɪ

Explanation:

We know that 2 atoms of K are present, so the total mass of the whole molecule will be (2×39)+12+(3×16) = 138u. So, from above calculation we can say that formula unit mass of ZnOis 81u, formula unit mass of Na2O is 62u and formula unit mass of K2CO3is 138u.
