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 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m3 volume of copper Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m3 (c) Calculate the density of the British sovereign coin. kg/m3
