- Chalky, white crystals in mineral collections are often labeled borax, which has the molecular formula Na2B4O7 10H2O, when actually they are partially dehydrated samples with the molecular formula Na2B4O7 5H2O, which is more stable under the storage conditions. Real crystals of borax are colorless and transparent. (a) Calculate the percent mass that the mineral has lost when it partially dehydrates. (b) Is the percent boron by mass the same in both compounds?Cooper, Zach and Nate did this experiment dissolving 3.80 g of Cu(C2H3O2)2·H2O and adding 8.60 g NaC7H4SO3N·H2O (assume present in excess).

- Some salts make hydrates when there is moisture around. Some hydrate samples can absorb lights in visible legion. Therefore, they show some colors. Thus, hydrates can be used to detect the moisture in the environment. Let's say you are working in a laboratory with a group and you are the only student who has taken chemistry courses. Your laboratory received a sample of cobalt(II) chloride which has the formula CoCl2·xH2O. Let's say your boss asked you to find the formula of this hydrate salt sample since you are the only chemist there. From your laboratory experience, simply explain the experimental procedure you would follow to find the formula of this unknown sample. Then, use the given data for the calculation part. Mass of crucible: 32.27g Mass of crucible + unknown hydrate: 33.92 g Color of unknown hydrate: purple Mass of crucible + anhydrous form of hydrate: 33.41 g Color of anhydrous form: sky bluePhosphorus may be determined analytically by precipitating it as MgNH4PO4 followed by ignition to Mg2P2O7. What mass of Mg2P2O7 will be obtained from a 9.346 g sample of phosphate rock which contains 71.24% Ca3(PO4)2?The hardness of water (hardness count) is usually expressed in parts per million (by mass) of CaCO3, which is equivalent to milligrams of CaCO3 per liter of water. What is the molar concentration of Ca2+ ions in a water sample with a hardness count of 175 mg CaCO3/L? Write the answer in scientific notation like this 1.23 x 10^4 M.
- A 7.83-g geological sample, containing the mineral Boulangerite (Pb5Sb4S11) as the only lead-bearing compound, is subjected to chemical treatment in which the lead is quantitatively recovered as solid PbCl2. The mass of PbCl2 obtained is 4.05 g.What was the percentage (by mass) of Pb5Sb4S11 in the sample?1.What mass of Cu(IO3)2 can be formed from 0.650 g of CuSO4 · 5H2O?2. What mass of KIO3 is needed to convert the copper in 0.2750 g of CuSO4 · 5H2O to Cu(IO3)2?Jerry is a student completing the same experiment to analyze KAl(SO4)2 * xH2O. After the step where he heats the hydrate, cools the crucible, and measures the mass, he doesn't have time to repeat the steps of heating, cooling crucibles, and remeasuring the mass. What would result if the crystals are not completely dehydrated when he records the final mass of the anhydrous salt? (Select All apply) A) The amount of water in the product would be overestimated. B) The amount of water in the product would be underestimated. C) There would be no effect on the final result. D) the x value in the formula would be lower than the actual value. E) the x value in the formula would be higher than the actual value.
