Calculate The Density One of them Helium nuclei ( 4He )
Hinweis: Assumptions:
— The Helium nuclei claimed a Of circular cross-section Volumes
— Weight Proton = Weight Neutron = 1 u
Lösung: Es will be Various Steps Required:
- Density = m/V = m/(4/3·pi·r3)
- Weight of the Cereals: The Commission 2 Protons and 2 Neutrons, about. 4 u, 1 u = 1.66·10-27of which:, This means that 6.64·10-27of which:
- Radius of the Helium nuclei: r = 1.2·10-15·4(1/3) = 1.9049·10-15 m
- V = 4/3·pi·r3) = 2.895·10-44 m3
- Density = m/V = 2.293·1017 kg/m3 (Vgl. Water: 1000 kg/m3)
