The British gold sovereign coin is an alloy of gold and copper having a total mass of 7.988 g, and is 22-karat gold.
(a) Find the mass of gold in the sovereign in kilograms using the fact that the number of karats = 24 (mass of gold)/(total mass).
kg
(b) Calculate the volumes of gold and copper, respectively, used to manufacture the coin.
volume of gold m3
volume of copper m3
(c) Calculate the density of the British sovereign coin.
kg/m3
