Answer 1

PLZZ mark me as brainliest ☺️☺️☺️

Answer 2

Answer:

option C

Explanation:

1gm ion of Al³+ion = 27gm

However, 27gm is also the molar mass of aluminium and , we know there are 6.022 x 10²³particles of a substance in molar mass of a substance. So,

27gm of Al³+ = 6.022 x 10²³Al³+ ions

charge on one Al³+ = 3eC

So, charge on 6.022 x 10²³ Al³+ ions = 3eC x Na

Hence charge on 1g ion of Al³+ would be = 3/27 x Na x eC

So, the correct option is C ---> 1/9 Na e Coulombs

HOPE THIS HELPS YOU
