Question

What is the molar mass of CaCl2?

37.0 g/mole

54.0 g/mole

75.0 g/mole

1.11 x 102 g/mole

Answer 1

Answer: The molar mass of the given compound is
`1.11* 10^2 g/mol`

Step-by-step 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* 35.5 g/mol=111.07 g/mol\approx 1.11* 10^2 g/mol`

The molar mass of the given compound is
`1.11* 10^2 g/mol`
