Archimedes and golden crown 2 part question

[ramly]

The weight in the air of the crown and the piece of solid gold is the same

1) If the crown is made of gold and silver (density is less than that of the gold) is the apparent weight of the crown in water greater than, equal to, or less than that of the solid gold? Why?

2) What if the crown is made of gold and platinum, which has the higher density than gold?

Well, what do you know about buoyant forces?
