Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Suppose the O2 gas evolved by a certain chemical reaction taking place at 35.0°C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 48.7mL. Sketch of a gas-collection apparatus Calculate the mass of O2 that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases. = g
Item 3 3 of 16 > I Review I Constants I Periodic Table Avogadro's law states that the volume, V, of a gas is directly related to the number of moles, n, of the gas when temperature and pressure are constant: (Figure 1) Part A A cylinder, with a piston pressing down with a constant pressure, is filled with 2.00 moles of a gas (n1), and its volume is 47.0 L (V). If 0.300 mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of the gas inside the cylinder?

Question 10 2 pts A set amount of gas is put into a cube- shaped container (a box with all the side lengths the same). The amount of pressure (units = atm) on the gas depends upon the size of the box. The pressure of the gas is inversely proportional to the cube of the length of the sides of the box. A box with 4 inch sides will cause a pressure of 11.5 atm. How long should the sides of the box be if you want the pressure to be 22 atm? Round your answer to two places after the decimal. (If you know any chemistry, do not use those facts to solve those problems. I cannot guarantee this problems follows the rules of chemistry. Use method learned in this class to find the solution.)
