If 0.5 mole of silver salt is taken and weight of residuc obtained is 216 g (Ag = 108 gmol). Then which of the
following is are correct:
n=4
n = 2
Option 1
Option 2
M. wt. of silver
salt is 718 g/mol
M. wt. of silver
salt is 388 g/mol​

Answer 1

Explanation:

mass of 0.5 mole of silver =

No . of moles = Given mass / molar mass

mass = no. of moles × molar mass

= 0.5 × 108

= 54g
