1mol aluminium chloride gives 1mol aluminium and 3mol chloride
density equals mass divided by volume
d=m/v
m=v*d
=78.3*2.7
=211.41grams

Answer:
The answer to your question is below
Explanation:
Electronegativity is a measure of how strongly atoms attract electrons to themselves.
Process
Look for the electronegativity of each element and compare.
a) Cl = 3.16 F = 3.98 Fluorine has a higher electronegativity
b) Se = 2.55 O = 3.44 Oxygen has a higher electronegativity
c) N = 3.04 As = 2.18 Nitrogen has a higher electronegativity
d) Na = 0.93 Mg = 1.31 Magnesium has a higher electronegativity
