Question

calculate the moleculer mass of sodium carbonet

Answer 1

Molar mass of

Na2

CO3

(2×22.98976928g/mol Na)

+

(1×12.0107g/mol C)

+

(3×15.999g/mol O)

=

105.987 g/mol Na2

The molar mass of sodium carbonate is

105.987 g/mol

To calculate the molar mass of a compound, multiply the subscript of each element from the formula times the molar mass of the element. The molar mass of an element is its atomic weight (relative atomic mass) on the periodic table in g/mol.

Answer 2

Hey friend !!

Here is your answer.

--------------------------------------------------------

Molecular mass of Sodium = 23 g/mol

Molecular mass of Carbon = 12 g/mol

Molecular mass of Oxygen = 16 g/mol

Therefore,molecular mass of Na2CO3 =

==> 23 * 2 + 12 + 16 * 3

==> 106 g/mol
