Answer:
the mass of the sample of neon is 0.34 grams.
Step-by-step explanation:
To calculate the mass of a sample of neon (Ne) containing a certain number of atoms, you need to know the molar mass of neon and use Avogadro's number. The molar mass of neon (Ne) is approximately 20.18 grams per mole (g/mol), and Avogadro's number is approximately 6.022 x 10^23 atoms per mole.
Given that the sample contains 1.01 x 10^22 atoms, you can use these values to calculate the mass as follows:
1. Calculate the number of moles of neon:
Number of moles = Number of atoms / Avogadro's number
Number of moles = 1.01 x 10^22 atoms / (6.022 x 10^23 atoms/mol)
2. Calculate the mass of neon:
Mass = Number of moles * Molar mass
Mass = Number of moles * 20.18 g/mol
Now let's calculate the mass:
Number of moles = 1.01 x 10^22 atoms / (6.022 x 10^23 atoms/mol) ≈ 0.0168 moles
Mass = 0.0168 moles * 20.18 g/mol = 0.34 grams
