A piece of metal has a mass of 120 grams.if its volume is 8 cm3.what is its density?
density = mass/volume
To calculate the density of a material, you need to divide its mass by its volume.
Given:
Mass of the metal = 120 grams
Volume of the metal = 8 cm³
Density = Mass / Volume
Step 1: Convert the volume from cubic centimeters (cm³) to cubic millimeters (mm³) for consistency.
1 cm³ = 1000 mm³
So, the volume of the metal in millimeters cubed is:
Volume in mm³ = 8 cm³ * 1000 mm³/cm³ = 8000 mm³
Step 2: Now, we can use the formula to calculate the density.
Density = Mass / Volume
Density = 120 grams / 8000 mm³
Density = 0.015 grams/mm³
Thus, the density of the metal is 0.015 grams per cubic millimeter (g/mm³).
