What is the molar mass of citric acid (c6h8o7) and baking soda (nahco3)?
Rufina [12.5K]

The molar mass of citric acid (c6h8o7) is 192.124g/mol

The molar mass of baking soda (nahco3) is 84.007g/mol

The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample and is measured in moles. Molar mass is a mass property, not a molecular property of a substance.

Molar mass is the mass of 1 mole of the sample. To find the molar mass, add up the atomic masses (atomic weights) of all the atoms in the molecule. Use the masses listed in the periodic table or atomic weight table to determine the atomic mass of each element.
