Answer: The molar mass of the given compound is $1.11\times 10^2 g/mol$

Explanation:

In molecular formula of $CaCl_2$ there are two chlorine atoms and one calcium atom.

The atomic mass of the calcium = 40.07 g/mol

The atomic mass of chlorine = 35.5 g/mol

Molar mass of the guven compound is :

$40.07 g/mol + 2\times 35.5 g/mol=111.07 g/mol\approx 1.11\times 10^2 g/mol$

The molar mass of the given compound is $1.11\times 10^2 g/mol$
