To convert the mass of a compound to formula units, the conversion factor is Avogadro's number, 6.022 x10^23 formula units/ mol and its molar mass. In this case, we are given with 19.0 grams of magnesium chloride which has a mass of 95.21 g/mol. Hence the answer is 1.20 x 10^23 formula units.
The property that determines an atom;s ability to attract electrons shared in a chemical bond is electronegativity. The correct answer is C.
M/V=D
16.52/2.26=D
