Calculate the formula unit mass of nahco3. (at. mass of na=23u, h=1u, c=12u, o=16u)

Formula unit mass of is 84 u.

Explanation:

Formula unit mass can be calculated by the adding individual element mass in the formula of the compound.

The given compound -

From the given the atomic mass of each element in the given compound is as follows.

Atomic mass of sodium (Na) = 23 u

Atomic mass of Hydrogen (H) = 1 u

Atomic mass of carbon (c) = 12 u

Atomic mass of oxygen (O) = 16 u

The number of atoms in the formula:

1 sodium atom =23 u

1 hydrogen atom = 1 u

1 carbon atom =  12 u

3 oxygen atom = 3 X 16 u = 48 u

_____________________________

Formula mass = 84 u

_______________________________

Therefore, Formula unit mass of is 84 u.
