What is the density of a block of unknown material with a mass of 19.07 g if the dimensions are:
length = 3.1 cm
height = 1.9 cm
width = 4.6 cm
Volume= 3.1 x 4.6 x 1.9 = 27.094cm3
Density=mass/volume
= 19.07g / 27.094 cm3
Density= 0.7038g/cm3 or 0.704g/cm3
To find the density of the block of unknown material, we can use the formula:
Density = Mass / Volume
Given that the mass of the block is 19.07 g, we need to find the volume of the block first.
The volume of a rectangular block can be calculated by multiplying its length, height, and width:
Volume = Length x Height x Width
Substituting the given values:
Volume = 3.1 cm x 1.9 cm x 4.6 cm
Next, multiply the values to find the volume:
Volume = 22.354 cm³
Now that we have the mass (19.07 g) and the volume (22.354 cm³), we can calculate the density:
Density = 19.07 g / 22.354 cm³
Calculating this gives the density:
Density ≈ 0.854 g/cm³
Therefore, the density of the block of unknown material is approximately 0.854 g/cm³.
