A 1.0 g sample of a pure organic compound containing chlorine is fused with `Na_(2) O_(2)` to convert chlorine to NaCl. On dissolving the sample in water and precipitating with `AgNO_(3),` it gives `1.96 g of AgCl.` If the molecular weight of organic compound is 147, how many chlorine atoms does each molecule contain?

A

1

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
Moles of Ag Cl = moles of chloride `( 1. 96)/(143.5) = 0.01 136 ,` Moles of organic compound `= (1)/(147) = 6. 8 xx 10 `
Chlorine atoms in ech moleculae of organic compound `= (0.0136)/(6.8 xx 10 ^(-3)) = 2 `
