Beakers (a), (b), and (c) are representations of tiny sections (not to scale) of mixtures made from pure benzene and pure water. Select which beaker gives proper representation of the result when the two pure substances are mixed.
Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20C is 54.6 g/100 g. At 80C, its solubility is 66.1 g/100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20C. (a) Is the mixture homogeneous? If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? (b) How many more grams of magnesium chloride are needed to make a saturated solution at 80C?
Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?

When you walked in to lab today, you noticed that your partner group had a 0.05432 ml mixture sample of sand and water in a beaker. When your group began the lab to separate the mixture in to different weight boats, you thought it would be very difficult to remove the sand. As a result, you added another 5.2ml of water to assist with removing it. A. Which separate method should be used to quickly and effectively separate the two substances. Explain why you chose this method. B.Determine the number of significant figures in your original sample. C.How much total mixture did you have after adding additional water.(provide the equation, calculate the answer and the final answer rounding to the correct number of significant figures.
