The king wants to pick out a new crown but only wants one made of 100% pure gold, not gold plated or mixed with other metals. Can you help him find his new gold crown?
The volume of each crown is 60 cm3
Densities of Metals
Lead – 11.34 g/cm3
Gold -19.3 g/cm3
Silver -10.5 g/cm3
Platinum - 21.4 g/cm3
Copper - 8.9g/cm3
D = M / V
A = 680.4 g
B = 534 g
C = 1,158 g
D = 1,284 g
