Question

calculate the formula unit mass of Na₂CO₃ (Sodium carbonate)

Answer 1

the formula mass of sodium bicarbonate is
(2*23)+(12)+(16*3)=106

Answer 2

The formula unit mass of Na₂CO₃ is 106 u.

Explanation:

In this case, we have given chemical formula of sodium carbonate. We need to find the formula unit of mass of sodium carbonate. It is also known as washing soda, soda ash etc. Formula unit mass of any chemical substance gives the measure of atomic masses of all the atoms in a compound.

Atomic mass of sodium (Na) is 23. For 2 moles atomic mass of sodium is 46. Atomic mass o carbon is 12 and for oxygen it is 16.

So,

$Na_2CO_3=2\times 23+12+3\times 16$

$Na_2CO_3=106\ u$

So, the formula unit mass of Na₂CO₃ is 106 u. Hence, this is the required solution.
