In lab they were able to collect the required data (above) buthad to finish the lab for homework. Once at home they forgot how to completethe calculation. Would you kindly help them with their calculation?What is the hydration number of this hydrate?

Acetylene C2H2 gas is often used in welding torches because of the very high heat produced when it reacts with oxygen O2 gas, producing carbon dioxide gas and water vapor. Calculate the moles of oxygen needed to produce 1.6mol of carbon dioxide. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant figures.
Acetylene (C2H2) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen (O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of acetylene needed to produce 0.060 of carbon dioxide. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
Commercial ibuprofen tablets contain 200 mg of ibuprofen each. The commercial tablets have the active ingredient (ibuprofen) in addition to several other additives (e.g. starch, sucrose, etc) to assist in digestion. There are 6 tablets that are used in the experiment. The maximum amount of available ibuprofen is (6 x 200 mg) = 1200 mg. Six pills Pure Ibup (after m.p. recrys.) Crude ibup.

Does it mean that the substance is impure, or perhaps isn't even ibuprofen at all? (Racemic mixture:75-77C, Enantiomer:52-53C)
