Two general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different. (c) Heat the crucible again, and then reweigh it.

To help farmers and gardeners , commercial fertilizers have a big three -number "NPK" label on the bag that gives the amounts of three key plant nutrients: nitrogen , phosphorus and potassium. For example , a bag of "-10-10-10" fertilizer has 10% by mass nitrogen , 10% by mass potassium as potash (K2O), and 10% by mass phosphorus as phosphate (P2O5). Suppose a certain fertilizer has the following composition. What should the first (nitrogen) number on the bag label be? That is, calculate the the percent by mass of nitrogen in this fertilizer. Round your answer to the nearest percent.

Many solids used in the lab come with different variations for different purposes. For example, EDTA has a formula of C1oH16N2O8 (292.2438 g/mol) but to improve the solubility of EDTA in water, the one we used in the lab is EDTA disodium salt dihydrate "C10H14N2N22O8 •2H20 " (Molar mass: 372.24 g/mol)where there are two sodium atom and two water molecule attached to the EDTA, therefore, when calculating the molar mass of EDTA, we need to add the mass of two sodium atoms and two water molecule mass.
