Calculate the energy needed to convert three moles of sodium atoms in the gaseous state to sodium ios. The ionization energy of sodium is 495 kJ `mol^(-)`.

A

`1485 kJ`

B

`495 kJ`

C

`148.5 kJ`

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
Energy needed to convert 1 mole of sodium (g) to sodium ions `= 495 kJ`
`:.` energy needed to convert 3 mole of `Na(g)` to `Na^(+)` ions `= 495 xx 3 = 1485 kJ`
