Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 9.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol.

The number of electrons in the given amount of silver are

Explanation:

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

Given mass of silver = 9.0 g

Molar mass of silver = 107.87 g/mol

Putting values in above equation, we get:

We are given:

Number of electrons in one atom of silver = 47

According to mole concept:

1 mole of an element contains number of particles

So, 0.0834 moles of silver contains number of electrons

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

for points guys
