The quantitative significance of take a deep breath varies, of course, with the individual. When one person did so, he found that he inhaled 2.951022 molecules of the mixture of mostly nitrogen and oxygen, which we call air. Assuming this mixture has an average molar mass of 29g/mol, what is his apparent lung capacity in grams of air?
At its boiling point (280°C) and at atmospheric pressure, phosphorus has a gas density of 2.7gL1 . Under the same conditions, nitrogen has a gas density of 0.62gL1 . How many atoms of phosphorus are there in one phosphorus molecule under these conditions?
Combustion of hydrocarbons such as butane ( C4H10 ) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous butane into gaseous carbon dioxide and gaseous water. Suppose 0.480kg of butane are burned in air at a pressure of exactly 1atm and a temperature of 10.0°C . Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits.
The following data were obtained when a test tube containing barium chloride hydrate was weighed before and after heating. The heating process drove off the water that was in the sample, producing an anhydrous salt. a) Mass of an empty test tube = 18.42g b) Mass of the test tube containing hydrate (before heating) = 20.75; c) Mass of the test tube containing anhydrous salt (after heating) = 20.41g The general formula of barium chloride is BaCl2 · nH2O, where n is the number of water molecules. The hydrate described by the data above either has a value of n=1; n=2; or n =3. Calculate the mass percent of water for each of these possible values of n
Combustion of hydrocarbons such as methane (CH4) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous methane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.380kg of methane are burned in air at a pressure of exactly 1atm and a temperature of 18.0°C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. = L
See the example in Introduction for set-up of calculations. Calculate the number of (a) moles of N, and (b) atoms of N in 12.7 g of nitrogen gas, N2. You do not need to include units in your answer, as they have already been included below, and use MM of N2 = 28.0134 g/mol. Type your answers in as an exponential expression (e.g. 1.23E-2 instead of 0.0123), where appropirate, and round your answers to three significant figures. moles
