Out of Al, Zn, Mg and Fe which is the densest element?

Text Solution

AI Generated Solution

To determine which element among Aluminium (Al), Zinc (Zn), Magnesium (Mg), and Iron (Fe) is the densest, we can follow these steps: ### Step 1: Understand Density Density is defined as mass per unit volume (Density = Mass/Volume). The element with the highest density will have the greatest mass for a given volume. ### Step 2: Look Up the Densities of Each Element We need to find the densities of Aluminium, Zinc, Magnesium, and Iron. The approximate densities are as follows: - Aluminium (Al): 2.70 g/cm³ ...
