which is the molar mass of bf3?\n10.81 g/mol\n29.81 g/mol\n48.81 g/mol\n67.81 g/mol
Answer
Explanation:
Step1: Find atomic masses
The atomic mass of B (boron) is approximately 10.81 g/mol, and the atomic mass of F (fluorine) is approximately 19.00 g/mol.
Step2: Calculate molar mass of BF₃
The formula for BF₃ has 1 boron atom and 3 fluorine atoms. The molar mass $M$ of BF₃ is $M = 1\times10.81+3\times19.00$. $M=10.81 + 57.00=67.81$ g/mol.
Answer:
67.81 g/mol
