Question

calculate the molecular mass of the Na2CO3(Na-23,C-12,O-16)​

Answer 1

Answer:

106

Explanation:

23 ×2 + 12 ×1 + 16×3 = 106

Answer 2

Explanation:

The molar mass of sodium carbonate is 105.987 g/mo

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 Na2CO3

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