- 3.122 What type of reasoning were we using when we developed the equation for dilution, MiVi=MfVf ?arrow_forwardPenicillin V was treated chemically to convert sulfur to barium sulfate, BaSO4. An 8.19-mg sample of penicillin V gave 5.46 mg BaSO4. What is the percentage of sulfur in penicillin V? If there is one sulfur atom in the molecule, what is the molecular weight?arrow_forwardZinc acetate is sometimes prescribed by physicians for the treatment of Wilsons disease, which is a genetically caused condition wherein copper accumulates to toxic levels in the body. If you were to analyze a sample of zinc acetate and find that it contains 3.33 1023 acetate ions, how many grams of zinc acetate must be present in the sample?arrow_forward
- Bacterial digestion is an economical method of sewage treatment. The reaction is an intermediate step in the conversion of the nitrogen in organic compounds into nitrate ions. What mass of bacterial tissue is produced in a treatment plant for every 1.0 104 kg of wastewater containing 3.0% NH4+ ions by mass? Assume that 95% of the ammonium ions are consumed by the bacteria.arrow_forwardNatural waters often contains relatively high levels of calcium ion, Ca2+, and hydrogen carbonate ion (bicarbonate), HCO3, from the leaching of minerals into the water. When such water is used commercially or in the home, heating of the water leads to the formation of solid calcium carbonate, CaCO3, which forms a deposit ('scale') on the interior of boilers, pipes, and other plumbing fixtures. Ca(HCO3)2(aq) --> CaCO3(s) + CO2(g) + H2O(l) If a sample of well water contains 2.0 X 10-3 mg of Ca(HCO3)2 per milliliter, what mass of CaCo3 scale would 1.0ml of this water be capable of depositing?arrow_forwardThe news that calcium deficiencies in women’s diets may contribute to the development of osteoporosis (bone weakening), has made the use of dietary calcium supplements become increasingly popular. Many of these calcium supplements consist of nothing more than calcium carbonate, CaCO3. When a calcium carbonate tablet is ingested, it dissolves by reaction with stomach acid, which contains hydrochloric acid, HCl. The balanced equation is: CaCO3 (s) + 2 HCl (aq) --> CaCl2 (aq) + H2O (l) + CO2 (g) Based on the reaction above, how many grams of HCl are required to react with a 500 mg CaCO3 tablet?arrow_forward
- EDTA, which is short forethylenediaminetetraacetic acid, is a chemical used inthe textile industry to prevent metal impurities fromchanging the colours of dyed products. Th e empiricalformula for EDTA is C5H8NO4. Th e molar mass ofEDTA is 292.24 g/mol. What is its molecular formula?arrow_forward3.161 Potash is any potassium mineral that is used for itspotassium content. Most of the potash produced in theUnited States goes into fertilizer. The major sources ofpotash are potassium chloride (KCl) and potassium sulfate(K2SO4). Potash production is often reported as thepotassium oxide (K2O) equivalent or the amount of K2Othat could be made from a given mineral. (a) If KCl costs$0.55 per kg, for what price (dollar per kg) must K2SO4be sold to supply the same amount of potassium on aper dollar basis? (b) What mass (in kg) of K2O containsthe same number of moles of K atoms as 1.00 kg of KCl?arrow_forward1.) If 6.0 grams of CaCO3 reacts with excess HCI, what mass of water should be formed? The balanced eqaution is:CaCO3 + 2HCI -----> CaCI2 + H2O + CO2 2.) oil of wintergreen, C8H8O3, is prepared when methanol, CH3OH, is reacted with salicylic acid, C7H6O3. What is the percent yield of a reaction in which 15.3 g of oil of wintergreen is collected after 16.3 g of salicylic acid is reacted with an excess of methanol? CH3OH + C7H6O3 -------> C8H8O3+ H2Oarrow_forward
- When 7.045 g of one of the hydrates of sodium sulfate (Na2SO4) was heated to drive off its water of hydration, the residue of anhydrous sodium sulfate has a mass of 4.674 g. What is the value of x in the formula for the hydrate, Na2SO4•xH2O?arrow_forwardA fertilizer railroad car carrying 34,300 gallons of commercialaqueous ammonia (30% ammonia by mass)tips over and spills. The density of the aqueous ammoniasolution is 0.88 g>cm3. What mass of citric acid,C(OH21COOH21CH2COOH22, (which contains three acidicprotons) is required to neutralize the spill? 1 gallon = 3.785 L.arrow_forwardThe chemical formula of tyrosine (a building block of proteins) is C9H11NO3.
