How do you determine the mass of sodium?

Answer 1

The relative Atomic Mass of sodium (Na) is 22.990. You can find the atomic mass of any element by looking on the Periodic Table of the elements. Sodium is located on the first column, left hand side.

Answer 2

it depends on the isotope of the element, there are a few variables in calculating the atomic mass

generally, on a decent periodic table, it will have an atomic mass for a number that look something like 121.76 (this is the case of antimony), you get the atomic mass by adding the number of protons and neutrons together, the atomic mass on your periodic table is a decimal because it is the average between all of the different atomic masses of all the isotopes, so lets say you had sodium 18, since sodium (Na) has 11 protons, this is a constant, it is a constant because sodium wouldn't be sodium if it didn't have 11 protons(the number of protons defines what element that atom is) then you just add the number of neutrons

hope this helped!

Answer 3

Add up the relative atomic masses of the atoms in the formula, Na2SO4. (Pardon the lack of subscripts).

Na = 23 so 2 x 23 = 46

S = 32

O = 16 so 4 x 16 = 64

46 + 32 + 64 = 142

It is more correct to say the relative formula mass of sodium sulfate is 142, because it is an ionic compound and does not contain molecules, though it would have been called molecular mass in the past.

Answer 4

Just subtract the the atomic mass from the number of protons and round

or it has 12 protons.

Answer 5

D=M/V

so in turn, M=DxV

M=mass

V=volume

D=density

Answer 6

The atomic weight (not mass) of sodium is 22,989 769 28(2).

Answer 7

The relative atomic weight of sodium is 23 and of chlorine is 35.5. Therefore the relative molecular weight of NaCl is 58.5.

Answer 8

22.989
