Question

Which is the molar mass of BF3?

Answer 1

The answer is 67.82 g/mol

Answer 2

Answer:

Molar mass of $BF_{3}$ is 67.805 g.

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\times$18.998 g) = 67.805 g
