Question

If energy required for the ionization of 0.2 g atom of Na atom is x kJ then the energy required (in kJ) to ionize 2.3g of Na atom ​

Answer 1

Answer ⇒  11.5x kJ.

Explanation ⇒ Ionization means converting the sodium atom into isolated gaseous ion.

For 0.2 gm of the Sodium atom, amount of energy released to convert it into isolated gaseous atom = x kJ.

∴ For 1  gm of the Sodium atom, amount of energy released to convert it into isolated gaseous atom = x/0.2 kJ.

∴ For 2.3 gm of the Sodium atom, amount of energy released to convert it into isolated gaseous atom = 2.3x/0.2 kJ

= 11.5x kJ.

Hence, energy released to convert sodium atom into isolated gaseou ion is 11.5x kJ.

Hope it helps.
