Answer 2

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
Molar mass of Na2CO3

(2×22.98976928g/mol Na)+(1×12.0107g/mol C)+(3×15.999g/mol O)=105.987 g/mol Na2CO3
