boron trichloride is BCl3. so add up the molar masses of Boron + 3 times the mass of chlorine periodic table for reference: ptable.com

ok so b has a molar mass of 9.012 and cl has a molar mass of 35.453 and theres 1 atom of B so 9.012 * 1 and 3 atoms of cl so 35.453 * 3 = 106.359 and then we add the 2 to get 115.371 g / mol ?

Vocaloid:

be careful, Boron is B not Be molar mass of boron is 10.81 not 9.012 but otherwise your logic is correct
