Density of Mn is more/ less than Fe.

Text Solution

AI Generated Solution

To determine whether the density of manganese (Mn) is more or less than that of iron (Fe), we can follow these steps: ### Step 1: Understand the concept of density Density is defined as mass per unit volume. It can be mathematically expressed as: \[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \] ### Step 2: Compare the atomic masses of Mn and Fe - The atomic mass of manganese (Mn) is approximately 54.94 g/mol. ...
