1. Find the molar mass of water (H₂O):
* Hydrogen (H) has a molar mass of 1.01 g/mol.
* Oxygen (O) has a molar mass of 16.00 g/mol.
* Molar mass of H₂O = (2 * 1.01 g/mol) + (1 * 16.00 g/mol) = 18.02 g/mol
2. Multiply the molar mass by the number of moles:
* Mass of 2.00 mol H₂O = 2.00 mol * 18.02 g/mol = 36.04 g
Therefore, the mass of 2.00 mol of H₂O is 36.04 grams.
