Final answer:
To find the density of an object submerged in water, you can use the formula: Density of object = Mass of object / Volume of object. Measure the mass of the object and the volume of water it displaces, then calculate the density by dividing the mass by the volume.
Step-by-step explanation:
To find the density of an object submerged in water, you can use the following formula:
Density of object = Mass of object / Volume of object
To measure the volume of the object, you can submerge it in water and measure the amount of water it displaces. The weight of the object in air can be measured using a scale. Once you have the mass and volume of the object, you can calculate its density.
For example, let's calculate the density of a 240-g rock that displaces 89.0 cm³ of water:
- Measure the mass of the rock, which is 240 g.
- Measure the volume of the water displaced by the rock, which is 89.0 cm³.
- Plug the values into the formula: Density of object = Mass of object / Volume of object.
- Density of object = 240 g / 89.0 cm³.
- Calculate the density: Density of object ≈ 2.70 g/cm³.
