Your answer is CORRECT.
Please watch the video below to learn why.
Let’s examine this choice.
Here is the original question:
Select the system that contains the maximum number of atoms. (Atomic mass: N = 14 g/mol, H = 1 g/mol, O = 16 g/mol, He = 4 g/mol), (NA = 6 x 1023).
What You Should Remember
A mole is a counting unit.
Every mole contains the same number of representative particles.
Different substances have different representative particles.
The mole concept connects microscopic particles to measurable amounts of matter.
Think Like a Chemist
Chemists rarely count individual atoms or molecules.
Instead, they count moles, just as we count eggs by the dozen or paper by the ream.
Understanding the mole allows chemists to work with unimaginably large numbers of particles using ordinary laboratory measurements.
