What is equivalent weight of NaHCO3?

The equivalent weight of NaHCO3 (sodium bicarbonate) is calculated by dividing the molar mass by the number of replaceable hydrogen ions (equivalents) in the compound. The molar mass of NaHCO3 is approximately 84 grams per mole. Since NaHCO3 has one replaceable hydrogen ion, its equivalent weight is also 84 grams per equivalent. This value is used in stoichiometry calculations to determine the amount of a substance needed to react with a given number of equivalents of another substance.
