Molar mass of Ne = 20g
Mass of 1 atom of Ne =
Molar mass/Avagadro no.
No =20 / 6.022*10²³g
Molar mass of Ca = 40 g
Number of particles in 4 g of Ca = 4/40*6.022*10²³ = 6.022*10²² atoms
Therefore, number of atoms of Ne same as 4 g of Ca = 20*6.022*10²²/6.022*10²³
=20/10
=2 g
================================
Answer: 2g of Ne has the same no. of atoms as 4g of Ca.
