Explanation:
Mass of compounds = Moles of compound × Molecular mass of compound
a) Moles of LiCl = 2.345 mol
Molecular mass of LiCl = 42.5 g/mol
Mass of 2.345 moles of LiCl = 2.345 mol × 42.5 g/mol = 99.6625 g
b) Moles of acetylene = 0.0872 mol
Molecular mass of acetylene= 26 g/mol
Mass of 0.0872 moles acetylene= 0.0872 mol × 26 g/mol = 2.2672 g
c) Moles of sodium carbonate= 
Molecular mass of sodium carbonate= 106 g/mol
Mass of sodium carbonate
= 
= 3.498 g
d) Moles of fructose = 
Molecular mass fructose= 180 g/mol
Mass of fructose
= 
e) Moles of 
Molecular mass of 
Mass of fructose
= 
F - Fluorine
Explanation:
Fluorine is the atom that is most able to attract electrons to itself among the choices. The ability of an atom to attract electron to itself is called electronegativity.
- Electronegativity is a measure of the relative tendency with which atoms of an element attracts valence electrons in a chemical bond.
- Fluorine is the most electronegative element on the periodic table.
- According to Pauling's table on electronegativities of elements, it has a value of 4.0.
- This is the highest on the periodic table of elements.
