Study Notes

Density Triangle Overview

Density Triangle helps understand the relationship between mass, volume, and density.
Mass is measured in grams (g).
Volume can be measured in cubic centimeters (cm³) or milliliters (mL).
Density is expressed in grams per cubic centimeter (g/cm³).

Finding Mass

To calculate mass:
- Use the formula: Mass (g) = Density (g/cm³) x Volume (cm³).

Finding Volume

To determine volume:
- Use the formula: Volume (cm³) = Mass (g) / Density (g/cm³).

Finding Density

To compute density:
- Use the formula: Density (g/cm³) = Mass (g) / Volume (cm³).

Steps to Find Density of an Irregular Object

Measure the mass of the irregular object using a balance.
Record the mass in grams.
Fill a graduated cylinder with enough water to cover the object.
Record the initial volume of water in milliliters (mL).
Carefully place the object into the graduated cylinder with water.
Record the new volume in milliliters after adding the object.
Subtract the initial volume from the new volume to find the object's volume.
Record the volume of the object alone in milliliters.
Use the density formula to find the object's density.
Include units for mass and volume in the final answer for clarity.
