Question

A compound MBr4 has a relative formula mass of 439

What is the relative atomic mass of M (Br=80)

Answer 1

119

Step-by-step explanation:

because the molecular mass of MBr can be found by adding the individual atomic masses of the molecule

Molar mass of M + 4(Molar mass of Br)= Molar mass of

MBr

Molar mass of M +4(80)= 439

Molar mass of M +320 = 439

Molar mass of M = 439 -320

Molar mass of M =119
