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

Hi friend
--------------
Your answer
-------------------

Water = H2O

Number of molecules in one mole of water = 6.022 × 10²³ [Avogadro's constant]

Given number of molecules = 2.52 × 10²³

So,
------

Number of moles =
\frac{2.52 \times 10 {}^{24} }{6.022 \times 10 {}^{23} }  \\  \\  = 4.184 \: (approximately)
