25 4. In an experiment a student was asked to measure the density of solid titanium. She was given a small flask and determined the mass to be 23.574 gwhen empty and dry. She then did the following steps. a. She completely filled the flask with water (VaskVH) and weighed the full flask, recording a mass of 25.817 g at 25 °C. At this point, the volume of water added is equal to the total volume inside the flask. The density of water at 25 °C is 0.99704 g/cm3. b. She poured out the water and dried the flask. She then added some pieces of titanium to it. The flask plus the titanium had a mass of 27.404 g. Leaving the titanium in the flask, she completely filled the flask the rest of the way with water. The mass for the flask with the titanium +water was measured to be 28.799 g. From the data given, calculate the following to the correct number of significant figures.

107 A soft drink can’s label indicates that the volume of the soda it contains is 12 oz or 355 mL. There is probably some empty space at the top of the can. Describe what you can measure and how that measurement allows you to determine the actual density of the soda.
You have a gas, one of the three known phosphorus-fluorine compounds (PF3, PF3, and P2F4). To find out which, you have decided to measure its molar mass. (a) First, yon determine that the density of the gas is 5.60 g/L at a pressure of 0.971 atm and a temperature of 18.2 C. Calculate the molar mass and identify the compound. (b) To check the results from part (a), you decide to measure the molar mass based on the relative rales of effusion of the unknown gas and CO2. You find that CO2 effuses at a rate of 0.050 mol/min, whereas the unknown phosphorus fluoride effuses at a rate of 0.028 mol/min. Calculate the molar mass of the unknown gas based on these results.

104 When a 0.817-g sample of a copper oxide is heated with excess hydrogen gas, a reaction takes place, and 0.187 g of water is formed. What is the apparent formula of the copper oxide?
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
6. The ideal gas law is a very simple mathematical relationship that relates several physical properties of a gas. This law is only valid when the behavior of a gas is idealized according to three principal assumptions. (i) State the three assumptions made about an ideal gas, and for each assumption (ii) explain which physical property of a gas would be affected if that assumption was not made.
Molecular weight of a volatile liquid A student had the following data:mass of volatile liquid: 0.317 gpressure: 1.076 atmtemperature C: 97.8volume of flask: 130.8 mLThe student calculated the molar mass to be 0.06857 g / mol which is impossible since H has a molar mass of 1.008 g / mol! The error that the student made was ... A) Not converting Celsius to Kelvin B) No errors were made. C) This unusual compound does have a fractional molar mass less than one and is the only known compound with such a mass. D) Not converting the volume from mL to L E) Using the wrong gas constant

For many purposes we can treat methane (CH) as an ideal gas at temperatures above its boiling point of -161. °C. Suppose the temperature of a sample of methane gas is raised from -24.0 °C to 18.0 °C, and at the same time the pressure is changed. If the initial pressure was 6.2 atm and the volume increased by 35.0%, what is the final pressure? Round your answer to 2 significant digits. | atm
