How many moles of carbon dioxide should be produced from the decomposition of 0.100 g of sodium bicarbonate?
Gre4nikov [31]
The chemical symbol for sodium bicarbonate is NaHCO3. Its molar mass is 84 g/mol. In each of one mol of sodium bicarbonate their is one mole of carbon dioxide with the molar mass of 44 grams per mol. We determine the number of moles in 0.10 g of sodium bicarbonate. 
                         n sodium bicarbonate = (0.10 g) / (84 grams / mol)
                                                            = 1.19 x 10-3 moles sodium bicarbonate
Therefore, there are also 1.19 x 10-3 moles of carbon dioxide.
