What is the molar mass of babr2? a. 217.2 g/mol b. 297.1 g/mol c. 354.5 g/mol d. 434.4 g/mol

Answer : The correct option is, (B) 297.1 g/mole

Explanation:

From the periodic table, we conclude that

The molar mass of barium (Ba) = 137.3 g/mole

The molar mass of bromine (Br) = 79.9 g/mole

Now we have to calculate the molar mass of .

The molar mass of = 137.3 + 2(79.9) = 297.1 g/mole

Therefore, the molar mass of is, 297.1 g/mole

The molar mass of is 297.1 g/mol

Explanation:

Molar mass of a compound is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

We are given a chemical compound having chemical formula

We know that:

Molar mass of barium = 137.3 g/mol

Molar mass of bromine = 79.9 g/mol

Molar mass of

Hence, the molar mass of is 297.1 g/mol
