A student is taking measurements on a rock that he found. Its mass was 15g, and he volume was 3ml. What was the rock’s density?

Page 4: Density Review and Classification of Matter. Density Density = Mass Volume Unit: g/ml

What is the volume of an object if the density is 10g/ml, and it’s mass is 30g?

Page 5: Density Review and Classification of Matter. Density Density = Mass Volume Unit: g/ml

What is the mass of an object if the volume is 10ml, and the density is 4g/ml?

Substances•Elements- simplest kind of matter

• Cannot be broken down into simpler• All one kind of atom.

•Compounds are substances that can be broken down by chemical methods

• When they are broken down, the pieces have completely different properties than the compound.• Made of molecules- two or more atoms

Page 9: Density Review and Classification of Matter. Density Density = Mass Volume Unit: g/ml

Mixtures•Made up of two substances.•Heterogeneous- mixture is not the same from place to place.

• Chocolate chip cookie, gravel, soil.•Homogeneous- same composition throughout.

• Kool-aid, air.•Every part keeps its properties.

Page 10: Density Review and Classification of Matter. Density Density = Mass Volume Unit: g/ml

Solutions•Homogeneous mixture•Can occur between any state of matter.

• Solid in liquid- Kool-aid• Liquid in liquid- antifreeze• Gas in gas- air• Solid in solid - brass• Liquid in gas- water vapor

•Like all mixtures, they keep the properties of the components.•Can be separated by physical means
