Question

what is the molar mass of the covalent compound bf3? bf3 = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar mass of B

The molar mass of B is 10.81 g/mol.

Step2: Identify molar mass of F

The molar mass of F is 19.00 g/mol.

Step3: Calculate molar mass of BF₃

There is 1 B and 3 F in BF₃. So molar - mass = 1×10.81+3×19.00 = 10.81 + 57.00 = 67.81 g/mol.

Answer:

67.81 g/mol
