You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143 nm. The masses of a proton, electron, and neutron are 1.67261024g,9.10941028g, and 1.67491024g, respectively. The volume of a sphere is 4r3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?

Noble gases (Group 18 in the periodic table) have the follow- ing volume concentrations in dry air: He, 5.24 ppm; Ne, 18.2 ppm; Ar, 0.934%; Kr, 1.14 ppm; Xe, 87 ppb. (a) A concentration of 5.24 ppm He means 5.24 µL of He per liter of air. Using the ideal gas law in Problem 1-16, find how many moles of He are contained in 5.24 µL at 25.00°C (298.15 K) and 1.000 bar. This number is the molarity of He in the air. (b) Find the molar concentrations of Ar, Kr, and Xe in air at 25°C and 1 bar. S ■ Tell me what you want to do AaBbCcDc AaBbCcDc AaBbC AaBbCct AaB AaBbcct AaBbCcD Normal 1 No Spac...
