Please please with the data table from the image attached please 1) Using the ideal gas law, calculate your experimental value of R (the gas constant) for each trial. (Remember, the pressure is the AP from your data table.) 2) Calculate the average and relative range of your R values 3) Calculate the % error of your average R
The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had 300.g of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.
