Question

calculate the molecular mass of BeCl

Answer 1

be mass 4

cl mass 35.5

add both mass 35.5+4=39.5

Answer 2

Answer:

44.5

Explanation:

Molecular mass of BeCl = Atomic mass of Be + Atomic mass of Cl

Atomic mass of Be = 9

Atomic mass of Cl = 35.5

Molecular mass of BeCl = 9 + 35.5

                                        = 44.5

Hope this helps! :)
