Question

The energy required to convert all atoms present in
1.2 g magnesium to Mg2+ ions if IE, and IE2, of
magnesium are 120 kJ mol-1 and 240 kJ mol-1
respectively
1) 18 kJ
(2) 36 kJ
3) 360 kJ
(4) 24 kJ

pls explain it​

Answer 1

Answer:

18kJ maybe....i am not surr

Answer 2

Answer:

24 g of Mg = 1 mole = 360 kJ/mol

1.2 g of Mg = 0.05 mole = 0.05 x 360/1 = 18 kJ
