What is the total electric charge of 2.5 kg of (a) electrons and (b) protons?

a

b

Explanation:

Generally the number of electron in the given mass is  mathematically evaluated as

Here  m_e is the mass of electron with value

    =>  

       =>  

The total electric charge is mathematically represented as

Here e is the charge on a single electron with value  

 So

The  negative sign is because we are considering electron

Generally the number of  protons in the given mass is  mathematically evaluated as

Here  m_p is the mass of electron with value

    =>  

       =>  

The total electric charge is mathematically represented as

Here p is the charge on a single proton with value
