<h3>Answer:</h3>
Density = 1.22 g.mL⁻¹
<h3>Solution:</h3>
Data Given:
Mass = 22.4 g
Volume = 18.3 mL
Density = ??
Formula used;
Density = Mass ÷ Volume
Putting values,
Density = 22.4 g ÷ 18.3 mL
Density = 1.22 g.mL⁻¹

Answer: The elements that have the lowest electronegativity are the VIII A elements or noble gases. These elements have a theoretical electronegativity of zero. These elements are stable in their electron configuration there is not force moving the noble gases to gain any electrons.
Explanation:
D.) Edmond Locard. He formulated the basic principle that there will be a transfer of material if one object touches another. This material may contaminate a specimen and make it useless as forensic evidence.
