Experiment 1: A student in a lab measured the mass of 380 mL of regular Coca Cola and the mass of 380 ml of Diet Coca Cola. He found the mass of regular Coca Cola to be 384 g, and the mass of diet Coca Cola to be 370g What physical property of both drinks can you calculate based on the data obtained in Experiment 17

c) A metal sample has a mass of 7.56 g. The sample is placed into a graduated cylinder previously filled with 20.00 mL of water (enough to cover the sample). If the final volume in the cylinder is 21.68 mL, what is the density of the substance? Consult Table 1.4 on page 19 of the textbook to identify the metal.

Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. mL of a clear liquid. The liquid is heated in a flask until it boils, which starts to happen at 66.2 °C. As the liquid boils, the temperature continues to rise, until the last of the liquid boils away at 76.0 °C. • Sample B is 100. g of a coarse grey powder with a faint unpleasant smell. 15. mg of the powder are put into a very thin tube and heated. The powder begins melting at 66.2 °C. The temperature stays constant as the powder slowly melts. After the last of the powder melts, the temperature starts to rise again, eventually reaching 76.0 °C. Is sample A made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide." Is sample B made from a pure substance or a mixture? If the description…
Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. mL of a clear liquid. The liquid is heated in a flask until it boils. The vapor that rises off the boiling liquid is collected for 10 minutes and cooled until it condenses into a separate beaker. The density of the liquid that remains in the flask is then measured, and turns out to be 1.04 g/mL. The density of the liquid that boiled off turns out to be 0.77 g/mL. Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is divided into two smaller 25.0 g subsamples, and the volume of each subsample is measured. The volume of the first is 48.2 cm³ and the volume of the second is 58.1 cm³. When the experiment is repeated with a new 50.0 g. sample, the volume of the two 25.0 g subsamples is 52.2 cm³ and 50.8 cm³.
