Question

The charge on 1 gram ions of Al3+ is : (NA = Avogadro number, e = charge on one electron)

A

$\frac{1}{27}$ NAe coulomb

B

$\frac{1}{3}$ × NAecoulomb

C

$\frac{1}{9}$ × NAecoulomb

D

3 × NAecoulomb

Answer

3 × NAecoulomb

Explanation

Solution

(4)

1 gram ion = 1 mole

charge on 1 mole Al3+ is = 3 × e (NA ).
