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 [tex]BaBr_2[/tex].
The molar mass of [tex]BaBr_2[/tex] = 137.3 + 2(79.9) = 297.1 g/mole
Therefore, the molar mass of [tex]BaBr_2[/tex] is, 297.1 g/mole
Answer: The molar mass of [tex]BaBr_2[/tex] 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 [tex]BaBr_2[/tex]
We know that:
Molar mass of barium = 137.3 g/mol
Molar mass of bromine = 79.9 g/mol
Molar mass of [tex]BaBr_2=[137.3+(2\times 79.9)]=297.1g/mol[/tex]
Hence, the molar mass of [tex]BaBr_2[/tex] is 297.1 g/mol
