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 ✕ 10^3 kg/m3. Determine the volume of gold in a 14.5 karat gold necklace that has a weight of 1.03 N.
