If Epsom salt,
MgSO, · ¤H2O, is heated to 250 °C, all the water of hydration is lost. On heating a 1.590-g sample of the hydrate, 0.777 g of
MgSO, remains. How many molecules of water occur per formula unit of
MgSO4?
molecules
Mn. S,O. n H20 is the general formula of a certain hydrate. When 234.9 g of the compound is heated to drive off the water, 209.9 g of anhydrous compound is left. Further analysis shows that the percentage composition
of the anhydrate is 36.38% Mn, 21.24% S, and 42.38% 0.
(Hint: Treat the anhydrous compound and water just as you have treated elements in calculating X in the formula of the hydrate.)
(Use an asterisk to enter the dot in the formula. If a subscript is 1, omit it.)
a. Find the empirical formula of the anhydrous compound.
b. Find the empirical formula of the hydrate.
Researchers obtain the following data from experiments to find the molecular formula of benzocaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54-g sample of benzocaine with excess O2 forms 8.49 g of CO2 and 2.14 g H2O. Another sample of mass 2.35 g is found to contain 0.199 g of N. The molar mass of benzocaine is found to be 165 g/mol. Find the molecular formula of benzocaine.
