Question

71 gm of chlorine combines with a metal giving 111gm of its chloride . atomic weight of metal

Answer 1

ANSWER
>>>>>>>>>>>>>>>>>>>>>>>>>

METAL ARE MONOATOMIC
CHLORINE IS DIATOMIC

LET THE METAL BE x AND ITS WEIGHT BE y

REACTION ----

2x + Cl2 =======> 2 xCl

2y + 71 =====> 111
2y + 71 = 111
2y = 111 - 71
2y = 40
y = 20

=> ATOMIC WEIGHT OF METAL IS 20
IF IT IS MONOVALENT

&

y = 111-71
y = 40

ATOMIC WEIGHT 40 IF IT IS DIVALENT
