-31 The mass of an electron is 9.11 × 10¬3ª kg. If the de Broglie wavelength for an electron in a hydrogen atom is 3.31 x 10-10 m, how fast is the electron moving relative to the speed of light? The speed of light is 3.00 × 108 m/s. Express your answer numerically as a percentage of the speed of light.
