Question:
The chloride of an element
Z reacts with water according to the following equation.
ZCL(4) (l) + 2H(2)O(l) >
ZO(2) (s) + 4HCL(aq)
A 1.304g sample of
ZCL(4) was added to water.
The solid
ZO(2) was removed by filtration and the resulting solution was made up to 250cm(cubed) in a volumentric flask. A 25.0cm(cubed) portion of this solution
was titrated against a 0.112 M(molarity) of Sodium Hydroxide, of which 21.7cm(cubed) were required to reach the end point.

Use this information to calculate the number of moles of HCL produced and hence the number of moles of
ZCL(4) present in the sample.
Calculate the relative molecular masss, Mr, of
ZCL(4).
From your answer deduce the relative atomic mass of, Ar, of element
Z and hence its identity.
I've tried everything and i keep getting astronomical number for the Mr of ZCL(4)
