QUESTION:
A sterling silver bracelet, which is 92.5% silver by mass, has a volume of 25.6 cm3 and a density of 10.2 g/cm3. (1.8, 1.9, 1.10, 3.5, 6.4) Sterling silver is 92.5% silver by mass.a. What is the mass, in kilograms, of the bracelet?b. How many atoms of silver are in the bracelet?c. Determine the number of protons and neutrons in each of the two stable isotopes of silver:
ANSWER:Solution 10CIStep 1 of 3:Given:Mass percent of Sterling silver = 92.5%.Volume of bracelet = 25.6 cm3Density = 10.2 g/cm3a. Here, we are asked to find the mass, in kilograms, of the bracelet.We know the formula for density: Denisty = This can be rewritten as: Mass = Density volume = 10.2 g/cm325.6 cm3 = 261.12 g. We have got mass in g, now let’s convert to kg 1 kg = 1000 gSo, the conversion factor is: Thus, the mass in kg will be: = 216.12 g = 0.216 kg.Hence, the mass of bracelet in kg is 0.216 kg.________________
