What is the molar mass of sodium oxygen oxalate #Na_2C_2O_4#?
Sodium oxalate has a molar mass of
atomic weight of element
Based on the chemical formula, we have 2 sodium atoms. The atomic mass would have to be multiplied by 2 to obtain a mass of 45.98g/mol
Next, you have 2 carbon atoms, so you would multiply the atomic mass of C by 2 to obtain a mass of 24.02 g/mol
Finally, since there are 4 atoms of oxygen, the atomic mass of O has to be multiplied by 4 to get a value of 64.00 g/mol.
Now you want to add the mass of each atom together to obtain the molar mass of the entire compound:
