The mass of a positron is approximately 9.1093826(16) × 10−31 kg. The positron and the electron are anti-particles of each other, and you can find out more about the positron at the Wikipedia article on that subject. A link to their post can be found below. There is also a link to a related question on the nature of the positron. That's down there, too.
