What is the density of a block of unknown material with a mass of 15.86 g if the dimensions are:
length = 2.2 cm
height = 1.7 cm
width = 4.8 cm
mass = volume x density
mass = 15.86 g
volume = 2.2 x 1.7 x 4.8 = ? cc
1 cc = 1 mL.
To find the density of the block, you need to divide its mass by its volume. The formula for density is:
Density = Mass / Volume
First, let's calculate the volume of the block. The volume of a rectangular block can be determined by multiplying its length, height, and width. In this case, the dimensions are as follows:
Length = 2.2 cm
Height = 1.7 cm
Width = 4.8 cm
Volume = Length * Height * Width
So, Volume = 2.2 cm * 1.7 cm * 4.8 cm
Now, multiply the dimensions together:
Volume = 17.472 cm³
Now that we have the volume, we can calculate the density by dividing the mass by the volume:
Density = Mass / Volume
Given:
Mass = 15.86 g
Volume = 17.472 cm³
Density = 15.86 g / 17.472 cm³
Calculating this division will give you the density value of the block.
