The layer of earth that makes up about two-thirds of earths mass is the inner-mantle..
The molar mass of sodium is approximately 23 grams per mole.
32g
The mass number of an atom is the sum of its protons and neutrons. In this case, the mass number of the sodium atom with 11 protons and 12 neutrons would be 23.
mass (g) = atomic wight / Avogadro's number Avo = 6.022x10^23
To calculate the mass of 3.011 x 10^23 nitrogen atoms, first find the molar mass of nitrogen which is 14.01 g/mol. Then, divide the number of atoms by Avogadro's number (6.022 x 10^23) to get the number of moles. Finally, multiply the number of moles by the molar mass to find the mass of the atoms. The calculation would be 3.011 x 10^23 / 6.022 x 10^23 = 0.5 moles, then 0.5 moles x 14.01 g/mol = 7.005 grams.
The mass of the planet Earth is 5,972.10e24 kg. The radius of the Earth is 6 371 km.
Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths. Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.
About 75% of the Sun's mass is Hydrogen, 23% is Helium and the remaining 2% consists of heavier elements such as carbon and oxygen.
the mass number of sodium is 23
Sodium is a meta element. Atomic mass of it is 23.
An element's core properties are determined by the number of protons. 21 protons makes this element Scandium. The number of neutrons that Scandium has is 23 in its normal state. It makes this an isotope of Scandium.
