What is the molar mass of H₂CO₃?

To calculate the molar mass of a compound like H2CO3 (which is the chemical formula for carbonic acid), you need to sum the atomic masses of all the atoms in the molecule.

The molecular formula for carbonic acid (H2CO3) consists of:

2 hydrogen (H) atoms
1 carbon (C) atom
3 oxygen (O) atoms
Now, you can find the atomic masses of these elements from the periodic table:

Hydrogen (H) has an atomic mass of approximately 1.01 g/mol.
Carbon (C) has an atomic mass of approximately 12.01 g/mol.
Oxygen (O) has an atomic mass of approximately 16.00 g/mol.
To calculate the molar mass of H2CO3:

Molar Mass = (2 × Atomic Mass of H) + (1 × Atomic Mass of C) + (3 × Atomic Mass of O)

Molar Mass = (2 × 1.01 g/mol) + (1 × 12.01 g/mol) + (3 × 16.00 g/mol)

Molar Mass = 2.02 g/mol + 12.01 g/mol + 48.00 g/mol

Molar Mass of H2CO3 = 62.03 g/mol

So, the molar mass of carbonic acid (H2CO3) is approximately 62.03 grams per mole (g/mol).
