Final answer:
Approximately 1.56 x 10^19 electrons need to be transferred from an object to produce a charge of 2.50 C. This calculation is based on the charge of a single electron, which is -1.60 x 10^-19 C.
Step-by-step explanation:
The number of electrons that must be transferred to produce a charge can be calculated using the charge of a single electron, which is -1.60 x 10^-19 C. The formula to calculate this would be Q(e) = N x e, where Q(e) is the total electric charge, N is the number of electrons, and e is the charge of one electron. Hence, N = Q(e) / e. If we substitute the given total charge of 2.50 C and the charge of a single electron into the formula, we get N = 2.50 C / -1.60 x 10^-19 C. As a result, approximately 1.56 x 10^19 electrons would need to be transferred to produce a charge of 2.50 C.
