What is the molar mass of water (H2O)?
gpt
18.02 g/mol for H2O.
Explanation: The molar mass of a compound is calculated by adding the atomic masses of its constituent elements and multiplying them by their respective whole number ratios in the formula. For water (H2O), it is the sum of hydrogen's atomic mass (around 1 g/mol) multiplied by 2 (for H2), and oxygen's atomic mass (around 16 g/mol) once (for O).
