Alloys of gold are rated in karats, a dimensionless unit that is used to indicate the proportion of gold by weight in a gold-containing alloy. If an alloy is one part in twenty-four pure gold, then it is classified as one karat gold. The density of gold is 19.3 ✕ 103 kg/m3. Determine the volume of gold in a 13.0 karat gold necklace that has a weight of 1.83 N.

cm3
b. Mercury is commonly supplied in flasks containing 34.5 kg (about 76 Ib). What is the volume in liters of this much mercury?
C. A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density (in g/cm?) of a 200 g rock that displaces 81.0 cm³ of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on
Archimedes' principle.)
