DIMENSIONAL ANALYSIS, STANDARDS OF MEASUREMENT, CHEMICAL COMPOSITION & STOICHIOMETRY 6. The density of pure silver is 10.5 g/cm³ at 20.°C. If 5.25 g of pure silver pellets are added to graduated cylinder containing 11.2 ml of water, to what volume level will the water in the cylinder rise? Explain. 7. Calculate the mass of a pure aluminum sphere with a radius of 1.38 in. given that the density of aluminum is 2.70 g/cm³ and volume of a sphere = 4/3 nr³
1. Perform each of the following conversions, being sure to set up using dimensional analysis and clearly showing the appropriate conversion factors with proper units in each case. a. 0.501 km to centimeters b. 254.3 g to kilograms c. 2.75 kg to grams d. 2.75 kg to pounds e. 2.75 kg to ounces f. 534.1 g to pounds g. 1.75 lb to grams h. 8.7 oz to grams i. 45.9 g to ounces 2. For the masses and volumes indicated, calculate the density in grams per milliliter. (1 cm³ = 1 mL exactly) a. mass = 122.4 g; volume = 5.5 cm³ b. mass= 19,302 g; volume = 0.57 m³ c. mass = 0.0175 kg; volume = 18.2 mL d. mass=2.49 g; volume = 0.12 m³
Density Read Section 1.4 of the OpenStax text, "Chemistry". 4. For the masses and volumes indicated, calculate the density in grams per milliliter. (1 cm¹ = 1 mL exactly) a. mass=4.53 kg; volume = 225 cm³ b. mass=26.3 g; volume=; 25.0 ml c. mass= 1.00 lb; volume 500. cm³ = d. mass=352 mg; volume = = 0.271 cm³ 5. A material will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0 g/ml under many conditions, will a block of material having a volume of 1.2 x 104 in. and weighing 3.5 lb. float or sink when placed in reservoir of water? Explain.
