Answer:
The answer to your question is 1.83 x 10²⁵ particles
Explanation:
Data
particles of H₂O = ?
mass of H₂O = 546 g
Process
1.- Calculate the molar mass of Water
Molar mass = (2 x 1) + (1 x 16)
= 2 + 16
= 18 g
2.- Use proportions to find the number of particles. Use Avogadro's number.
18 g ---------------- 6.023 x 10²³ particles
546 g --------------- x
x = (546 x 6.023 x 10²³) / 18
3.- Simplification
x = 3.289 x 10²⁶ / 18
4.- Result
x = 1.83 x 10²⁵ particles

Answer:
C - show 7 neutrons in the nucleus
Explanation:
Use process of elimination:
-Answer A will not work because electrons are not in the nucleus.
-Answer B will change the atom's identity from nitrogen to fluorine; it will not work.
-Answer D will create a nitrogen ion, which is not what the prompt is asking for (an atom); it will not work.
The only logical answer is C, as that is the only one that is also true.
