How many atoms of neon are present in 1.30 moles of neon?

Question

Quizplus · Accepted Answer

We can use Avogadro's number, which represents the number of particles (atoms, molecules, etc.) in one mole of substance. Avogadro's number is approximately 6.02×10²³ particles/mol.

So, to find the number of atoms of neon in 1.30 moles of neon, we can use:

number of atoms = (moles of neon) x (Avogadro's number)

number of atoms = 1.30 mol x 6.02×10²³ atoms/mol

number of atoms = 7.83×10²³ atoms

Therefore, the answer is choice C: 7.83 × 10²³ atoms.
