Three elements X,Y,and Z form a Doberiener triad The ratio of the aotmic weight of x to theat of Z is 160 find the atomic weight of X,Y and Z |
|
Answer» Solution :Let the atomic WEIGHTS of X,Y and Z be `Z_(x),Z_(y)` and`Z_(z)` respectively `therefore (Z_(x))/(Z_(z))=(7)/(25)rarrZ_(x)=(7)/(25).Z_(z)rarr(1)` Given htat `Z_(x)+Z(z)`=160 `therefore (7)/(25).Z_(z)=160rarrZ_(z)=125` fromequation (1) `Z_(x)=(7)/(25).125=35` atomic weight of y is `Z_(y)=(35+125)/(2)=80` `[therefore` X,Y and Z form DOBEREINER TRAID] |
