Question

calculate the formula unit mass of zn where the mass of Z in is 65 and over 16 ​

Answer 1

Answer:

Explanation:

Answer: The formula unit mass of ZnO is 81u,  is 62u and that of  is 138u.

Explanation:

Formula unit mass is defined as the sum of the atomic masses of all atoms that are present in a formula unit of the given compound. It is calculated by adding the atomic masses of all the atoms that are present in one formula unit.

We are given:

Atomic mass of Zn = 65u

Atomic mass of Na = 23u

Atomic mass of K = 39u

Atomic mass of C = 12u

Atomic mass of O = 16u

Calculating the formula unit masses of the given compounds:

Hence, the formula unit mass of ZnO is 81u,  is 62u and that of  is 138u.
