<u>Answer:</u> The number of electrons in given amount of silver are
<u>Explanation:</u>
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
We have that The Density and Volume is given as
The factors that affect Density are Mass and Volume
From the question we are told that
The piece of wood shown above has a mass of 20 grams.
Wood parameters
2cm
5cm
3cm
Generally the equation for the Volume is mathematically given as
Generally the equation for the Density is mathematically given as
Therefore the factors that affect Density are Mass and Volume
