Question

The molar mass of Cr(OH)2 is:

a. 86.02 g/mole
b. 70.02 g/mole
c. 85.01 g/mole
d. 138.02 g/mole

Answer 1

The molar mass of
`Cr(OH)_2` is 86.02 g/mole .

Explanation:

The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.

The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.

From the below attached table, the Molar mass of
`Cr(OH)_2` is 86.0108 g/mol.
