- What is the total mass of oxygen in a single molecule of glucose? Express your answer in amu to 5 significant figures. HINT: Make sure your atomic mass for O has a precision of at least 5 sig figs; otherwise, your answe will not be correct. For example, do not use a value of 16 amu per oxygen atom for the atomic mass of O. That has too few sig figs.Quinine ( C20 H24 N2 O2) is the most important alkaloid derived from cinchona bark. It is used as an antimalarial drug. For quinine, pK, = 5.1 and pK, = 9.7 ( pKp = – log Kp). Only 1 g quinine will dissolve in 1920.0 mL of solution. Calculate the pH of a saturated aqueous solution of quinine. Consider only the reaction | Q+ H2O= QH+ + OH- described by pK, where Q = quinine. pH =A chemist combined chloroform (CHCI,) and acetone (C, H,O) to create a solution where the mole fraction of chloroform, Xchloroform, is 0.187.

How many kilograms of hard coal provide the same amount of heat as is available from 1.0 gallon of gasoline? Assume that thedensity of gasoline is 0.692 g/mL (the same as the density of isooctane).Hydrocarbons with 5 carbons (pentane) and 19 carbons (nonadecane) are liquids at room temperature. The molecules with 8, 9, and 10-carbons are "octane", "nonane", and "decane" and are common components of gasoline. The image below shows chemical equations for the combustion of the simplest hydrocarbon methane, 3-carbon propane, and 10-carbon decane. As you can see, the products are always carbon dioxide and water, just in larger amounts for larger hydrocarbons. Question: how many carbon dioxide molecules are formed from combustion of one molecule of decane?

Upload your step by step solution for A.A sample of hydrogen peroxide solution has a mass of 4.599 g. After reacting with the enzyme solution, the moles of oxygen are 0.00284 moles. What is the percent hydrogen peroxide in the solution?Which of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas. Overview of the experiment:
