What is the mass of 2.486 * 10^{24} atoms of neon? Select one:
a)83.33 g Ne
b)0.2046 g Ne
c)8.333 g Ne
d) 4.130 g Ne

The answer is A 83.33 g Ne

Explanation:

Used Avogadros Law

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
