Answer: The number of electrons in the given amount of silver are [tex]2.36\times 10^{24}[/tex]
Explanation:
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
Given mass of silver = 9.0 g
Molar mass of silver = 107.87 g/mol
Putting values in above equation, we get:
[tex]\text{Moles of silver}=\frac{9.0g}{107.87g/mol}=0.0834mol[/tex]
We are given:
Number of electrons in one atom of silver = 47
According to mole concept:
1 mole of an element contains [tex]6.022\times 10^{23}[/tex] number of particles
So, 0.0834 moles of silver contains [tex](47\times 0.0834\times 6.022\times 10^{23})=2.36\times 10^{24}[/tex] number of electrons
Hence, the number of electrons in the given amount of silver are [tex]2.36\times 10^{24}[/tex]
