Archimedes purportedly used his principle to verify that the king's crown was pure gold by weighing the crown while it was submerged in water. Suppose the crown's actual weight was 70.0 N . The densities of gold, silver, and water are 19.3 g/cm^3, 10.5 g/cm^3 and 1.00 g/cm^3, respectively. What would be its apparent weight if it were made of 75%% gold and 25%% silver, by volume?
