To determine the correct formula for a particular sample, a known amount of hydrate is heated to drive off the water. The data listed below were gathered in the experiment:
mass of dry crucible and lid : 17.639g
mass of crucible, lid , and hydrated SrCl2 (before heating) : 18.455g
mass of crucible, lid, and anyhydrous SrCl2 (After heating) : 18.304g
use the data to calculate:
a. mass of hydrated SrCl2
b. mass of (anyhydrous) SrCl2
c. Moles of SrCl2
d. mass of water liberated by heating
e. moles of water in hydrated sald
f. formula for hydrated SrCl2
please show work!
