What is the density of a block of unknown material with a mass of 17.02 g if the dimensions are:
length = 2.2 cm
height = 1.7 cm
width = 2.7 cm
volume = length x width x height = ? cc.
Then density = mass/volume = ? g/cc
To determine the density of a block of unknown material, you need two pieces of information: the mass and the volume of the block. In this case, you already have the mass, which is 17.02 g.
To find the volume of the block, you need to multiply its length, height, and width. So, the volume (V) can be calculated using the formula:
V = length × height × width
Plugging in the given dimensions:
V = 2.2 cm × 1.7 cm × 2.7 cm
Now, simply multiply these values to find the volume.
V = 8.926 cm³
Now that you have both the mass and the volume, you can calculate the density. Density (D) is defined as the mass (m) divided by the volume (V), expressed as:
D = m / V
Plugging in the given values:
D = 17.02 g / 8.926 cm³
Dividing the mass by the volume will give you the density of the unknown material in units of grams per cubic centimeter (g/cm³).
