How Much Water Does Cobalt Displace?

Click For Summary
SUMMARY

The volume of water displaced by 1.82 grams of cobalt, with a density of 8.9 g/mL, is calculated using the formula Volume = mass/density. Substituting the values, the volume displaced is 0.204 mL. Since cobalt's density is greater than that of water, it confirms that the object displaces a volume equal to its own when fully submerged. Additionally, the mass of the liquid displaced equals the mass of the cobalt object.

PREREQUISITES
  • Understanding of density and its formula (Density = mass/volume)
  • Basic knowledge of volume calculations in milliliters
  • Familiarity with the concept of displacement in fluids
  • Knowledge of the properties of cobalt and water
NEXT STEPS
  • Study the principles of fluid displacement in physics
  • Learn more about density calculations and their applications
  • Explore the properties of different metals and their densities
  • Investigate the relationship between mass and volume in various states of matter
USEFUL FOR

Students in chemistry and physics, educators teaching fluid dynamics, and anyone interested in material properties and displacement concepts.

Homework Statement


Calculate the volume of water, in milliliters, that would be displaced by 1.82 grams of cobalt, when cobalt's density is 8.9 g mL^-1.


Homework Equations


Density = m/v
Volume = m/d



The Attempt at a Solution


volume = m/d
Volume= 1.82 g/8.9 g mL^-1
Volume = 0.204 mL^-1?

I'm honestly stumped. Hopefully someone has some sort of idea of how to solve this.

I think your correct :). Because the object is totally submerged (density of Cobalt is greater than that of water), it displaces a volume in liquid equal to the volume of itself.

For future reference, the mass of liquid displaced is also equal to the mass of the object itself.
