<span>If volume = weight divided by density - we already know the weight is 15 grams, and that the density is 7.8 grams. We would plug this into the formula to get 15g divided by 7.8cm3 with proper units and significant figures - we would end up with 1.92cm cubed.</span>

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
120.38 g/mol is the answer
