Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 7.1 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mole.

The number of electrons in given amount of silver are

Explanation:

To calculate the number of moles, we use the equation:

We are given:

Given mass of silver = 7.1 g

Molar mass of silver = 107.87 g/mol

Putting values in above equation, we get:

Number of electrons in 1 atom of silver = 47

According to mole concept:

1 mole of an element contains number of particles

So, 0.066 moles of silver will contain = - number of electrons

Hence, the number of electrons in given amount of silver are
