Study Notes
Metric Conversions
- Draw the metric conversion staircase.
- 98.05 kL = 98,050 L
- 5.20 x 10-4 g = 0.520 mg

Applications of Metric Conversions, Density, and Dimensional Analysis
- Given a cube with a side length of 2.50 cm, calculate its volume in cm³ and liters.
- Formula for density: density = mass/volume
- Rearrange the formula to solve for volume: volume = mass/density
- Rearrange the formula to solve for mass: mass = density x volume
- Density of liquid water: 1.00 g/mL
- Given a 5.25 kg sample of aluminum and knowing the density of aluminum is 2.70 g/cm³, calculate the volume of the sample.
- Density of an object with dimensions 2.0 cm x 1.0 cm x 3.0 cm and a mass of 25.75 grams: 4.3 g/cm³
