Answer 1

Your answer is --

we know that

1 gram ion = 1 mol ion

Now ,

1 mol Al^+3 ion = NA ion

Now, charge on 1 gram Al^+3 ion is

3 × NA e coulomb

where , e = elementary charge ( 1.6×10^-19)

NA = Avogadro number ( 6.023×10^23)

Answer 2

Hey Friend ＼(^_^)／

We know that,

1 gm atom = 1 mole of Atom

so, charge on 1 mole of electron = NA × Charge on 1 e-

= 6.023 × 10^23 × 1.6 × 10^-19 C.

= 9.6368 × 10^4


Thus charge on one mole of Al^3+ ion = 3×96398

= 289104 C.
