Density and Chemistry Review

Explore the relationship between mass, volume, and density through practical examples and calculations. This guide includes scenarios such as determining the volume of a rock with a mass of 85g and a density of 3.1g/mL, calculating the mass of a plastic car with a known volume and density, and studying the densities of various substances like water, glycerol, and molasses. Understand the concepts of sinking and floating based on density values, and learn how to apply these principles in real-life situations.

  1. Density and Chemistry Review

  2. Mass, Volume and Density • If I have a rock with a mass of 85g and a density of 3.1g/mL, what would the volume be? • 27.4 mL

  3. Mass, Volume and Density • If I have a plastic car with a volume of 13mL and a density of 3.1g/mL. What would the mass be? • 40.3 g

  4. Mass, Volume and Density • I have a metal marble with a volume of 5 mL and a density of 15.3 g/mL. What would the mass be? • 76.5 g

  5. Mass, Volume and Density • I have snickers with a mass of 8.2 g and a volume of 7.5 mL. What would the density be? • 1.1 g/mL

  6. Mass, Volume and Density • If shredded paper has density of 0.5 g/mL, how much space would 140 g of paper take up? • 280 mL

  7. Mass, Volume and Density • What is the density of a gummy bear if the mass is 2.2g and the volume is 1.4 mL • 1.6 g/mL

  8. Sink or Float • Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL • Water has a density of 1.0 g/mL. Will glycerol sink or float in water? • Sink

  9. Sink or Float • Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL • Will glycerol sink or float in molasses? • Float

  10. Sink or Float • Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL • Will water sink or float in oil? • Sink

  11. Sink or Float • Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL • I have a snickers with a density of 1.2 g/mL Will it sink or float in oil? • Sink

  12. Sink or Float • Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL • If I have a die that sinks in glycerol but floats in molasses what do I know about the die? • It has a density greater than 1.3 g/mL but less than 1.4 g/mL
