An electron accelerated through a potential will gain a kinetic energy of 110eV (electron volts).
KE = 0.5mv^2
p = mv
therefore your momentum, p = sqrt(KE * m *2). To convert electron volts to Joules (SI unit of energy) multiply by 1.6x10^-19. So you have 1.76x10^-17 Joules of energy. The mass of an electron is 9.11x10^-31 kg so;
p = 5.66x10^-24 kg m/s
