These problems: n (the number of electrons transferred from one body to another) = 2.5 * 10 ^ 10 electrons.

Reference values: me (mass of one electron) = 9.1 * 10 ^ -31 kg.

The change in the mass of bodies can be calculated by the formula: Δm = n * me.

Calculation: Δm = 2.5 * 10 ^ 10 * 9.1 * 10 ^ -31 = 22.75 * 10 ^ -21 kg.

Answer: The mass of one body has increased by 22.75 * 10 ^ -21 kg; the mass of the other decreased by 22.75 * 10 ^ -21 kg.
