WebMass is related to energy by Δ E = mc2, so that the mass of the pion is m = Δ E / c2, or m\approx \text {100}\text { MeV/} {c}^ {2}\\ m ≈ 100 MeV/c2 . Discussion This is about 200 times the mass of an electron and about one-tenth the mass of a nucleon. No such particles were known at the time Yukawa made his bold proposal. Webkilograms. Problem 4 - An oxygen atom contains a total of 16 protons and neutrons and has a mass of 2.7x10-26 kilograms. What is the mass of a Top Quark in terms of the number of oxygen atoms? Answer: From Problem 1C, the Top Quark mass is 3.1 x 10-25 kilograms, and so the number of oxygen atoms needed to equal the mass of one Top Quark is 2.7x10 reading ma weather hourly
