🤓 Based on our data, we think this question is relevant for Professor Gulde's class at UB.

Solution: The mass of an electron is 9.11x10 -31 kg . If the de Broglie wavelength for an electron in a hydrogen atom is 3.31x10-10 m , how fast is the electron moving relative to the speed of light? The speed of light is 3.00 x 108 m/s . Express your answer numerically as a percentage of the speed of light.
