Mass, Density, Volume

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams (g) or kilograms (kg).

Front

What is density?

Back

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

Front

What is volume?

Back

Volume is the amount of space an object occupies, measured in cubic centimeters (cm³) or liters (L).

Front

How do you calculate the volume of a rectangular object?

Back

Volume = length × width × height.

Front

What is the formula for calculating density?

Back

Density = mass / volume.

Front

If an object has a mass of 100 g and a volume of 50 cm³, what is its density?

Back

Density = 100 g / 50 cm³ = 2 g/cm³.

Front

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

Back

Mass = Density × Volume.

Front

How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the mass in grams by 1000.

Front

What is the percent error formula?

Back

Percent Error = |(Measured Value - Actual Value) / Actual Value| × 100%.

Front

If the actual length of an object is 14.25 cm and the measured length is 12 cm, what is the percent error?

Back

Percent Error = |(12 - 14.25) / 14.25| × 100% = 15.79%.
