Unit 1 DA Review

Density can be found by

• dividing the mass by the volume of the object

• multiplying the mass by the volume of the object

• dividing the volume by the mass of the object

• adding the mass and the volume of an object

If an object has a density that is less than water's density what will happen to the object when placed in water?

• It will float

• It will sink

• More information is needed

• You cannot answer this question without knowing the exact mass and volume of the object.

Water has a density of 1 g/mL while oil has a density of 0.67g/mL. If water and oil are mixed what will the resulting solution look like?

• Water on top, oil on botyom

• Oil on top, water on bottom.

• Water and oil mixed
