WebApr 10, 2024 · The Electron Is So Round That It’s Ruling Out Potential New Particles. If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection. If an electron were the size of Earth, the experiment could detect a bump the size of a sugar molecule. Kristina Armitage/Quanta ...

2.2: The Sizes and Shapes of Organic Molecules

WebAboutTranscript. Even though molecules, proteins, viruses, and cells are all tiny, there are significant size differences between them. The diameter of a water molecule is roughly 0.28 nanometers. The diameter of the protein hemoglobin is roughly 5 nanometers. The diameter of the HIV virus is roughly 120 nanometers. WebV m = M ρ = 118.09 1.59 c m 3 m o l = 74.27 c m 3 / m o l. where M is the molar mass and ρ the density. From this, you find the volume of the molecule to be.
