Question

The current density number of free electron per metre cube in metallic conductor is of the order of what

Answer 1

To find density, we have to solve the equation for volume, or V. V = nRT / P. To incorporate mass, we can use the number of moles, or n. The number of moles equals the mass of the gas divided by the molecular mass. Molecular mass is the mass calculated by adding atomic masses in the chemical formul
