Question

How do you determine the theoretical mass of CaCl2​

Answer 1

The theoretical mass of $CaCl_2$ is ​110.

Explanation:

Mass of one atom of calcium = 40 .

Mass of one atom of chlorine=35.5 .

Hence , two atoms would be $35.5 \times 2=70.$

Therefore, mass of calcium chloride would be net sum both constituent atoms

= $40+70=110$

So the theoretical mass of $CaCl_2$ is ​110.

The theoretical mass is the measure of item coming about because of an ideal chemical reaction, and in this manner not equivalent to the sum you'll really get from a response in the lab. It is the measure of item coming about because of an ideal chemical reaction, and therefore not equivalent to the sum you'll really get from a response in the lab.
