What is the mass in grams of 2.00 × 10⁵ atoms of naturally occurring neon? A)6.07 × 10¹⁹ B)9910 C)797 D)3.32 × 10^-19 E)4040000

Question

Quizplus · Accepted Answer

The molar mass of neon is approximately 20.18 g/mol. Using Avogadro's number (6.022 × 10^23 atoms/mol), the mass of 2.00 × 10^5 atoms of neon can be calculated as follows: (2.00 × 10^5 atoms) / (6.022 × 10^23 atoms/mol) × 20.18 g/mol = 797 grams.
