0.4g of silver salt of a monobasic organic acid gave 0.26g pure silver on ignition

0.4 g of silver salt of a monobasic organic acid gave 0.26 g pure silver on ignition. The molecular weight of the acid is (atomic weight of silver = 108)

Options

(a) 59
(b) 72
(c) 90
(d) 104

Correct Answer:

59

Explanation:

Mass of silver salt = 0.4g.Mass of silver = 0.26 g. Eq.mass of silver salt/Eq.mass of silver = mass of silver salt/mass of silver. Eq.mass of silver salt = 0.4/0.26×108. E + 108 – 1 = 0.4/0.26×108. Therefore = 59.15.
