What is the mass of an aluminum cylinder with 0.234 in diameter and a length of 2.697
Lemur [1.5K]

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 = \frac{mass}{volume}

 Mass of the cylinder = density x volume

To calculate the volume of cylinder;

  Volume = π r² h

     radius of the cylinder = \frac{0.234}{2} = 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
