Question
1. Using the measured circumference (c= 21.3 cm) of the glass ornament, calculate the radius in cm. Formula for circumference of a sphere= 2(3.14) r. 2. Using the radius from above, calculate the surface area (cm^2) of the ornament. (Surface area= 4(3.14)r^2) 3. Calculate the mass of the silver that is in the glass ornament. (Final mass-Initial mass) Initial mass- 14.43 Final mass- 14.53 4. The density of silver is 10.5 g/cm^3. What is the volume of the silver metal lining the inside of the glass ornament? 5. Assume that the volume of silver in the ornament can be approximated by the following equation: Volume= Surface area x thickness. Calculate the approximate thickness of the silver lining in cm and convert the answer to picometers (1x10^12 pm= 1m). 6. If the radius of a silver atom is 160 pm, what is the diameter of a silver atom. How many silver atoms thick is the lining?
Silver Holiday Ornaments continued Questions 1. Using the measured circumference of the glass ornament, calculate the radius (in cm). The formula for the circumference of a sphere is 2nr (ivLumferenA - 21.3 cu E 2. Using the radius from above calculate the surface area (cm²) of the ornament. (. Surface area = 41r².) 3. Calculate the mass of the silver that is in the glass ornament. (Subtract mass of ball before and after the silver is added.) Inihal mass = 14.43 Fiual mass = 14.53 4. The density of silver is 10.5 g/cm3. What is the volume of silver metal lining the inside of the glass ornament? 5. Assume that the volume of silver in the ornament can be approximated by the following equation: Volume = Surface areax thickness. Calculate the approximate thickness of the silver lining in centimeters, and convert the answerto picometers (1x1012 pm = 1m). 6. If the radius of a silver atom is 160 pm, What is the diameter of a silver atom. How many silver atoms thick is the lining.
