Sodium has an atomic weight of 22.99 and therfore 9 moles has a mass of
206.91 g.
the mass number of sodium is 23
there is no such thing as an average mass of a sodium. sodium is an element. a sodium molecule's mass will therefore be exact in mass, never average.
The atomic mass of sodium is approximately 23 g/mol.
Sodium's atomic mass is 22.98977
The atomic mass of sodium is 22.989768 a.m.u.
The Relative Atomic Mass of Sodium is 23.
Sodium (Na) has an Atomic Mass of 22.989768.
Sodium is a meta element. Atomic mass of it is 23.
Sodium is a metal element. Atomic mass of it is 22.99.
The molar mass of sodium chloride is 58,44.
To find the number of moles in 120 grams of sodium, divide the given mass by the molar mass of sodium. The molar mass of sodium is approximately 23 grams per mole. Therefore, 120 grams of sodium is equal to 120/23 ≈ 5.22 moles of sodium.
The ratio mass of chlorine/mass of sodium is 1,5.
