1.54 x [tex]10^3[/tex] g is the mass of 4.60 x [tex]10^{25}[/tex] atoms of neon.
What are moles?
A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
1 mol of atoms = 6.02214076 × [tex]10^{23}[/tex]
Moles of neon in 4.60 x [tex]10^{25}[/tex] atoms = [tex]\frac{mass}{molar \;mass}[/tex]
[tex]\frac{4.60 X 10^{25}}{ 6.02214076 X 10^{23}}[/tex]
0.7638479709 = 76.38 mol
The molar mass of neon is 20 g/mol
76.38 mol x 20 g/mol
1.54 x [tex]10^3[/tex] g
