Density Graphs

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density?

Back

The unit of density is typically grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

If a substance has a mass of 20 grams and a volume of 4 mL, what is its density?

Back

Density = 20 g / 4 mL = 5 g/mL.

Front

What does a density graph represent?

Back

A density graph shows the relationship between mass and volume for a substance, illustrating how density remains constant regardless of the amount of substance.

Front

What is the relationship between mass and volume in a density graph?

Back

In a density graph, mass is typically plotted on the y-axis and volume on the x-axis, showing a linear relationship where the slope represents density.

Front

What does a steeper slope in a density graph indicate?

Back

A steeper slope indicates a higher density of the substance.

Front

What is the significance of the y-intercept in a density graph?

Back

The y-intercept represents the mass of the substance when the volume is zero, which is typically zero for most substances.

Front

How can you determine which substance is least dense from a density graph?

Back

The substance with the lowest slope (or the lowest value on the density scale) is the least dense.

Front

What is the volume of a substance with a mass of 12 grams and a density of 3 g/mL?

Back

Volume = Mass / Density = 12 g / 3 g/mL = 4 mL.
