QUESTION 7
The hydrated salt, MY2·xH2O, was heated strongly in a crucible to remove all the water
molecules of crystallization.
The data for this experiment are given in the table below.
Mass of empty crucible and cover 33.41 g
Mass of crucible, cover, and hydrated salt 36.93 g
Mass of crucible, cover, and anhydrous salt 35.92 g
Molar mass of anhydrous salt 178.96 g/mol
(i) Calculate the % composition by mass of water in the hydrated salt?
(ii) Determine the value of x?
(iii) M is in Period 4 of the Periodic Table of the Elements
If Y = NO3-
, identify the element M?
