Question

Which is the molar mass of BF3?

Answer 1

The answer is 67.82 g/mol

Answer 2

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
