Molecular Weight Of Oxalic Acid
Molecular Formula of Oxalic Acid
Before diving into its molecular weight, let’s first look at the molecular formula of h2c2o4, which is C₂H₂O₄. This formula tells us that one molecule of oxalic acid consists of two carbon atoms (C), two hydrogen atoms (H), and four oxygen atoms (O).
Atomic Weights of Elements
To calculate the molecular weight of oxalic acid, we need to know the atomic weights of the constituent elements. As of my last knowledge update in September 2021, the atomic weights of these elements are as follows:
- Carbon (C): Approximately 12.011 atomic mass units (amu)
- Hydrogen (H): Approximately 1.008 amu
- Oxygen (O): Approximately 15.999 amu
Calculation of Molecular Weight
Now, let’s calculate the molecular weight of h2c2o4 by summing the atomic weights of its constituent atoms:
- Carbon (C): 2 atoms × 12.011 amu = 24.022 amu
- Hydrogen (H): 2 atoms × 1.008 amu = 2.016 amu
- Oxygen (O): 4 atoms × 15.999 amu = 63.996 amu
Now, add these values together:
Molecular weight of oxalic acid = 24.022 amu + 2.016 amu + 63.996 amu ≈ 90.034 amu
So, the molecular weight of h2c2o4 is approximately 90.034 atomic mass units (amu) or 90.034 grams per mole (g/mol).
