Answer:

Molar mass of
BF_(3) is 67.805 g.

Step-by-step explanation:

Molar mass of a molecule is the sum of atomic masses of all constituting atoms.

In
BF_(3), there are one boron atom and three fluorine atoms.

Atomic masses of boron and fluorine are 10.811 g and 18.998 g respectively.

So molar mass of
BF_(3) = (10.811 g)+(
3*18.998 g) = 67.805 g
