What is the mass of 3.0 x 10^23 atoms of neon

The mass of neon for the given number of atoms will be 9.8 g.

Explanation:

We are given:

Number of neon atoms =

According to the mole concept:

number of atoms. are occupied in 1 mole of a substance.

So, will be occupied in =

To calculate the number of moles, we use the equation:

Moles of Neon = 0.49 moles

Molar mass of neon = 20 g/mol

Putting values in above equation, we get:

Hence, the mass of neon for the given number of atoms will be 0.49g.
