One mole of chlorine combines with certain weight of metal giving 111g of its chloride.the same amount of metal can displace 2g of hydrogen from an acid.the atomic weight of the metal is:plzzz. reply fast

let metal be x

Cl₂     +                     x   =       n* xCl    ( n  moles)

1 mole = 71g                             111g

91 cl = 35.5g)

see that as it replaces 2g H = replacing 2 moles of H or 2+ charge

thus metal has 2+ charge as Ca, Mg etc or 2 moles of metal like Na, K etc.....

as Cl ha 1- charge so  its two moles are used in the metal chloride as:

XCl₂   type ( for Ca type metals ) or   (but here it is this type - a quite logic)

2XCl  type (for Na type)

so weight of chloride = 111= 2* 35.5 + x

so x=40  here see that Ca and  K has this much mass bt  K has 1 charge so should hv used its two moles thus finally use weight would be 80g

bt used is 40 g.

so metal is Ca and its mass is 40 g
