0.33g
Explanation:
Given parameters:
Diameter of cylinder = 0.234cm
length = 2.697cm
unknown:
mass of the cylinder = ?
Solution:
To solve this problem, we know that density of the aluminium can be determined and it is a constant.
Density is the mass per unit volume of a substance
Density =
Mass of the cylinder = density x volume
To calculate the volume of cylinder;
Volume = π r² h
radius of the cylinder = = 0.12cm
Volume = 3.142 x 0.12² x 2.697 = 0.12cm³
Density of aluminium = 2.7g/cm³
Mass of the cylinder = 0.12 x 2.7 = 0.33g
