Answer: The molar mass of [tex]BF_3[/tex] is 67.81 g/mol
Explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
Atomic Mass of Boron (B) = 10.81 g
Atomic Mass of Flourine (F) = 18.99 g
Molecular mass of [tex]BF_3[/tex] = 1 (10.81)+3(18.99) g = 67.81 g
Thus molar mass of [tex]BF_3[/tex] is 67.81 g/mol
