The molar mass of BF3 is 67.81 g/mol
<em><u> Explanation</u></em>
- Molar mass is the mass of all atoms in a molecule in gram per mole.
- molar mass of a molecule is calculated by adding atomic mass of constituent atom
- use the periodic table to determine the atomic mass of each element in the molecule.
that is;
atomic mass of B = 10.81 g/mol
atomic mass of F = 19 g/mol
- since there 3 atoms of F in BF3 the atomic massof F in BF3= 3 x19 = 57 g/mol
- total molar mass of BF3 = 10.81 g/mol + 57 g/mol = 67.81 g/mol
