Imagine that the apparent weight of the crown in water is $w_{apparent}$ = 4.50n, and the actual weight is $w_{actual}$ = 5.00n. is the crown made of pure (100%) gold?
the density of water is $\rho_w$ = 1.00 grams per cubic centimeter. the density of gold is $\rho_g$ = 19.32 grams per cubic centimeter.
