Finding the Unknown... Scientists often solve the density for unknown objects. What is the Mystery Object if it's Mass is 18.58 g and Volume is 5.7 cm³?

• chlorite, 3.3 g/cm³

• quartz, 2.6-2.7 g/cm³

• gypsum, 2.3 g/cm³

• calcite, 2.7g/cm³

The Density of Water = 1 g/mL or 1 g/cm³. If an object's density is more than 1 g/cm³ it will sink. If an object is less than 1 g/cm³ it will float.

True or False: An object with a density of 0.2 g/cm³ will float in water.

• True

• False
