Answer:
Wc = 7.84 weight of crown
Ww = 7.84 - 6.86 = .98 weight of water displaced
Density = 7.84 / .98 = 8 crown is 8 X that of water
Since gold has a density of 19.3 that of water the crown is certainly not 100 percent (if any) gold

Answer:
177.213 grams
Explanation:
Given:
Total amount of water = 364 grams
Latent heat of fusion = 333 kJ/kg
Heat transferred = 62.2 kJ
The amount of water frozen = 62.2/333 = 0.186786 kg = 186.786 grams
Hence, the amount of water remained unfrozen = Total water - Amount of water frozen
the amount of water remained unfrozen = 364 grams - 186.786 grams = 177.213 grams
It must be boiled/heated to a high temp
