What is the molar mass of water (H2O)?
Sidana [21]

Answer:

The molar mass is: 18.02 g/mol.

Explanation:

  • Mass of two moles of Hydrogen atoms (H2) = 2x 1 g/mol = 2 g/mol.
  • Mass of one mole of water (H2O) = 2 g/mol + 16 g/mol = 18 g/mol.

1 mole of Hydrogen= 1.01, so if we have 2 moles of it here, that would be 2.02.

1 mole of Oxygen (that's all we have here)= 16.00

Once you add the two together (2.02+16.00), you will get 18.02.

I hope this made sense! Have a great day!
