What is the percent composition of NaHCO3?

Katarina [22]

Answer:- Na = 27.37%, H = 1.20%, C = 14.30% and O = 57.14%

Solution:- For the percentage composition of a compound, the atomic mass of each atoms times its subscript is divided by the molar mass of the compound and multiplied by 100.

The given compound is $NaHCO_3$ .

mass of Na = 22.99 g

mass of H = 1.008 g

mass of C = 12.01 g

mass of O = 3(16) = 48 g

Molar mass of compound = 22.99 g + 1.008 g + 12.01 g + 48 g = 84.008 g

percentage of Na = $(\frac{22.99}{84.008})100$

= 27.37%

percentage of H = $(\frac{1.008}{84.008})100$

= 1.20%

percentage of C = $(\frac{12.01}{84.008})100$

= 14.30%

percentage of O = $(\frac{48}{84.008})100$

= 57.14%
