What is the buoyancy of a 79g iron when it is put into water? (the known density of iron is 7.9 * 10 ^ 3kg / m ^ 3)

What is the buoyancy of a 79g iron when it is put into water? (the known density of iron is 7.9 * 10 ^ 3kg / m ^ 3)

The volume of iron block V Fe = m Fe / ρ Fe = 10 ^ - 5m ^ 3
F floating = ρ water GV drainage = 0.1N

What is the relationship between buoyancy and mass in Archimedes
The greater the mass, the greater the buoyancy? Or

The buoyancy of large volume and small mass is large, that is, what kind of large and light buoyancy

The mass of an iron block is 158g. When all the iron blocks are immersed in water, we can find: 1. The volume of the iron block; 2. The buoyancy of the iron block in water
(ρ Fe = 7.9x10 & sup3; kg / M & sup3;)
（g=10N/kg）

V = m / P = 0.02 M3
Because P iron is greater than p water, so the iron sink to the bottom
F floating = P iron GV row = 1.68n
