Part A How many electrons make up a charge of -40.0mu C ?

To find the number of electrons that make up a charge of , we need to use the fact that the charge of a single electron is Coulombs.The formula to calculate the number of electrons is:Number of electrons = Total charge / Charge of a single electronGiven:Total charge = = CCharge of a single electron = CPlugging in the values, we get:Number of electrons = C) / ( C)Simplifying the expression, we get:Number of electrons = Therefore, there are electrons that make up a charge of .
