Question

What is the molar mass of sodium carbonate, $$(Na_2CO_3)$$?

Answer 1

The molar mass of sodium carbonate is $$105.987 \ g/mol$$

Explanation:

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.

Molar mass of $$Na_2CO_3$$

$$(2\times 22.98976928\ g/mol \ Na)+(1\times 12.0107\ g/mol \ C)+(3\times 15.999\ g/mol \ O)=105.987\ g/mol \ Na_2CO_3$$
