Assuming each of copper atom has 1 free electron . Estimate the number of free electron in 1g of copper. What is the charge possessed by these free electron?

Question

Answer

Number of Free Electrons in 1g of Copper:
- The molar mass of copper is approximately 63.5 g/mol.
- This means that 1 mole of copper contains Avogadro's number of atoms, which is 6.022 x 10^23 atoms.
- Since each copper atom has 1 free electron, there are also 6.022 x 10^23 free electrons in 1 mole of copper.
- To calculate the number of free electrons in 1g of copper, we need to divide the mass of copper by its molar mass and then multiply by Avogadro's number.

Charge Possessed by the Free Electrons:
- The charge possessed by each electron is the elementary charge, which is approximately 1.6 x 10^-19 coulombs.
- Since each free electron in copper possesses this charge, the total charge possessed by all the free electrons in 1g of copper can be calculated by multiplying the number of free electrons by the elementary charge.
- This will give us the total charge possessed by the free electrons in 1g of copper.
