Moles Ca = 4 g / 40 = 0.,1
= moles Na
Mass Na = 0.1 mol x 23 g/mol = 2.3g
= moles Na
Mass Na = 0.1 mol x 23 g/mol = 2.3g

Answer: The mass of sodium containing same number of atoms is 2.3 grams.
Explanation:
To calculate the number of moles, we use the equation:
.....(1)
Moles of calcium:
Given mass = 4 g
Molar mass = 40 g/mol
Putting values in above equation:
We need to calculate the mass of sodium having same number of atoms which means having same number of moles.
So, moles of sodium = 0.1 mole
For Sodium:
Molar mass = 23 g/mol
Putting values in equation 1:
[tex]0.1mol=\frac{\text{mass of sodium}}{23g/mol}\\\\ \text{Mass of sodium}=2.3g[/tex]
Hence, the mass of sodium containing same number of atoms is 2.3 grams.
