Question

Calculate the formula unit mass of CaCl2

​

Answer 1

Answer:

Formula unit mass of CaCl2=40+71=111g. Answer: The formula unit mass of calcium chloride is 111 amu. Explanation: Formula unit mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the empirical formula of a compound

Answer 2

Formula unit mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the empirical formula of a compound. It is expressed in amu.

We know that

Atomic mass of calcium = 40 amu

Atomic mass of chlorine = 35.5 amu

Formula mass of CaCl2=40+(2*35.5)=111g.

Hence, the formula unit mass of calcium chloride is 111 amu.
