You then heat the sample in order to remove the water and find the weight of the anhydrate to be 3.52 g. The first thing to do is to determine the moles of water that were in the sample, #(4.13-3.52)# #"g" * ("1 mole water")/("18.0 g") = 0.034# #"moles"#, You now go on to determine the moles of the anhydrous salt, #BaCl_2#, #3.52# #"g" * ("1 mole"BaCl_2)/("208.2 g") = 0.017# #"moles"#, The mole ratio between the water and the anhydrous salt is, #("moles of water")/("moles of anhydrate") = 0.034/0.017=2#. In our example, 0.5 moles of water 0.1 moles copper sulfate = 5:1 ratio. First, calculate the number of moles of anhydrous salt are present in 7.93 g. To do this you need to determine the molecular weight of K2CO3. 0.0074074 x 100% = 0.74% (expressed using 2 significant figures ). 7.1, under low temperature and high pressure, forming a solid similar to ice [1].It looks like ice, but starts burning when an open flame is brought close to it; methane hydrate is often called "fiery ice." Can I Decrease My Running Routine and Still Stay Lean?
