Calculate The Formula Unit Mass of Zno, Na2O And K2CO3. Give Atomic Mass Of Zn = 65u Na = 23u K = 39u C = 12u O = 16u

Answer: The formula unit mass of ZnO is calculated as the sum of the atomic mass of zinc i.e. 65u  and the atomic mass of Oxygen i.e. 16u. Hence, the value comes out to be 81u. The formula unit mass of Na₂O is calculated as the sum of the atomic mass of two atoms of sodium i.e 2x23u and the atomic mass of Oxygen i.e 16u. Hence, the value comes out to be 62u. The formula unit mass of K₂CO₃ is calculated as the sum of the atomic mass of  two atoms of potassium i.e  2x39u and the atomic mass of carbon i.e 12u and the atomic mass of three Oxygens i.e 3 x16u. Hence, the value comes out to be 138u.
