SI units, metric conversion & density

Front

What is the SI unit of mass?

Back

The SI unit of mass is the kilogram (kg).

Front

How many milligrams are in a gram?

Back

There are 1,000 milligrams (mg) in a gram (g).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 48 grams and a volume of 24 cm³, what is its density?

Back

Density = 48 g / 24 cm³ = 2 g/cm³.

Front

Convert 28 °C to Kelvin.

Back

K = °C + 273.15; therefore, 28 °C = 301.15 K.

Front

What is the volume of an object with a mass of 50 grams and a density of 2 g/cm³?

Back

Volume = Mass / Density = 50 g / 2 g/cm³ = 25 cm³.

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 is constant.

Front

How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the number of grams by 1,000.

Front

What is the density of a substance with a mass of 14 g and a volume of 2 cm³?

Back

Density = 14 g / 2 cm³ = 7 g/cm³.

Front

What is the SI unit for volume?

Back

The SI unit for volume is the cubic meter (m³), but liters (L) are also commonly used.
