I need help with a density problem?

Question

the density of bismuth metal is 9.8g/cm3. What is the mass of a masss of a sample of bismuth that displacess 65.8 mL of water?

ps can u tell me what "displace" means in here?

Answer 1

"displace" here means the volume of water that flows out as the metal is dip into the medium(water). So here the volume of the water that flows out is equivalent to the volume of the bismuth metal.

1 cm3 = 1 mL

so,

65.8 mL = 65.8 cm3

the basic formula;

density = mass/volume

mass = density x volume

mass (bismuth) = 644.84 g
