The percent by mass sugar of a solution : 11.07%

<h3>Further explanation</h3>

Given

mass of sugar = 12.45 g

mass of water = 100 g

Required

The percent by mass

Solution

Mass of solution :

\tt mass~sugar+mass~water=12.45+100=112.45~g

Percent mass of sugar :

\tt \%mass=\dfrac{mass~sugar}{mass~solution}\times 100\%\\\\\%mass=\dfrac{12.45}{112.45}\times 100\%=11.07\%

liubo4ka [24]

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
