She places the liquid in a flask and puts the flask in a boiling water bath, which vaporizes the liquid and fills the flask with gas. She closes the flask, reweighs it, and obtains the following data: Volume of flask (V) = 213 mL Mass of flask+gas = 78.416 g T=100°C P=754 torr (760 torr in 1 atmosphere) Mass of empty flask = 77.834 g Calculate the molar mass of the liquid, carefully converting to appropriate units, where necessary.

4 The mixture used in today's experiment was prepared as a 1:1:1 mixture (by mass) of sand, salt, and salicylic acid. Do your results for the mass of each recovered solid indicate a 1:1:1 composition of the mixture? Explain your response.
Willa weighs a clean, dry, empty crucible and finds it to have a mass of 95.83 g. After putting a spoonful of an unknown hydrate into it, she finds that the mass has increased slightly to 99.87 g. She heats the crucible and its contents, and finds that the mass has dropped to 97.22 g. Willa is told by her teacher that the molar mass of the anhydrous salt is 75.65 g.
The Law of Combining Gas Volumes A compound containing only chlorine and oxygen is decomposed into its elements, resulting in 1.71 g of chlorine and 1.54 g of oxygen. a) If the density of chlorine gas is 3.17 g/L, what volume of chlorine gas was generated? b) If the density of oxygen gas is 1.43 g/L, what volume of oxygen gas was generated? c) Based on the last two calculations, what is the formula of the original compound?
Calculate the edge length in m and the volume in L for a cubical box that will “exactly” contain 4.32x1023 atoms. Assume the diameter of the Argon atom is 3.4 Å (1.000 Å = 1.000x10-10 m). Assume the atoms touch each other so that the closest distance between atomic centers (nuclei) is 3.4 Å and the atoms fill the box with MANY layers of Argon atoms.Note: a cubical box needs only one measurement to be defined because each edge of a cube is exactly the same length, l,so that the volume of the box, V = l3.
