Answer:
SiBr₄= 347.7 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
SiBr₄:
Atomic mass of Si = 28.1 amu
Atomic mas of Br = 79.9 amu
There are four atoms of Br = 79.9 ×4
There is one atom of Si = 28.1 × 1
Gram formula mass of SiBr₄:
SiBr₄ = 79.9 ×4 + 28.1 × 1
SiBr₄= 319.6 + 28.1
SiBr₄= 347.7 g/mol
