Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in units such as g/cm³ or kg/m³.

Front

How do you find the volume of a liquid?

Back

You can find the volume of a liquid using a graduated cylinder or a beaker.

Front

What is the formula to calculate volume if you know mass and density?

Back

The formula to calculate volume is V = M/D, where V is volume, M is mass, and D is density.

Front

How do you calculate the volume of a rectangular solid?

Back

The volume of a rectangular solid is calculated by multiplying its length, width, and height (Volume = length x width x height).

Front

What is the density of an object if its mass is 40.5 g and its volume is 15.0 mL?

Back

The density is calculated as Density = Mass/Volume = 40.5 g / 15.0 mL = 2.7 g/mL.

Front

What is the unit of density in the metric system?

Back

The unit of density in the metric system is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the number of grams by 1000.

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to density and volume; as density increases, mass increases if volume remains constant.

Front

What is the volume of 150 grams of lead with a density of 11.3 g/cm³?

Back

The volume can be calculated using the formula V = M/D, which gives V = 150 g / 11.3 g/cm³ = 13.3 cm³.

Front

What equipment is commonly used to measure the volume of liquids?

Back

Graduated cylinders and beakers are commonly used to measure the volume of liquids.
