(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol.

(b) Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 109 electrons already present?

Step 1

a) It's necessary to determine the number of electrons in a small, electrically neutral silver pin of mass 10g. Molar mass of silver is known$M=107.87\frac{g}{m}ol$ . It is possible to determine the number of atoms inside the pin

$N}_{Ag}=\frac{{m}_{\pi n}}{M}\cdot 6\cdot {10}^{23$ atoms

$N}_{Ag}=5.56225\cdot {10}^{22$ atoms

Inside every atom there a 47 electrons, it's necesarry to calculate the total amount of charge.

$N}_{e}=47{N}_{Ag$

$N}_{e}=2.61\cdot {10}^{24$ elektrons

$q}_{e}=47\cdot {N}_{e$

${q}_{e}=435087C$

Step 2

It's necessary to calculate the number of electrons in 1 mC.

$N=\frac{1mC}{1.67\cdot {10}^{-19}C}=5.99\cdot {10}^{15}$ electrons

Now, we can determine the number of electrons for even$10}^{9$ .

$n=\frac{N}{\frac{{N}_{e}}{{10}^{9}}}=2.29$ for ever $10}^{9$ electons
