1. Find the molar mass (MM) of the hydrate (cobalt acetate tetrahydrate).
MM Co(C2H3O2)2: 177.02g (anhydrate)
+ MM 4H2O: 72.06g (water)
MM Co(C2H3O2)2 * 4H2O = 249.08g (hydrate)
2. Find the percent water of hydrate. Divide the mass of water by the mass of hydrate (anhydrate + water = hydrate).
72.06g
249.08g x 100%
Percent water of hydrate is 28.93%.
Finding Molar Mass
# atoms Element A * Atomic Mass Element A = Mass A
# atoms Element B * Atomic Mass Element B = Mass B
... etc.
Add up all of the mass values and you have the molar mass of the substance.

What does 4H2O tell you about the number of molecules and the total number of atoms of each element?
The "4" means that there are 4 water (H2O) molecules. The subscript of 2 on hydrogen means that there are two Hydrogens per molecule of water, so there are 8 hydrogens and 4 oxygens in all, since Oxygen has a subscript of 1.
What are the products of burning hydocarbons?
It depends upon the extent of combustion take propane as an example Complete Combustion: C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(l) Incomplete Combustion: C3H8(g) + 3.5O2(g) --> 3CO(g) + 4H2O(l) Very Incomplete Combustion: C3H8(g) + 2O2(g) --> 3C(s) + 4H2O(l) Products of Complete = Carbon Dioxide + Water Products of Incomplete = Carbon Monoxide + Water Products of Very Incomplete = Amorphous Carbon (soot) + Water
What is the balanced equation of the combustion of propane to produce carbon dioxide and water vapor?
The balanced chemical equation for the combustion of propane (C3H8) is: C3H8 + 5 O2 -> 3 CO2 + 4 H2O. This equation shows that when one molecule of propane reacts with five molecules of oxygen, it produces three molecules of carbon dioxide and four molecules of water.
