How many moles are in 180.0 grams of H2O?

Answer 1

The molar mass of H2O (water) is approximately 18.015 g/mol.

To calculate the number of moles in 180.0 grams of H2O, you divide the given mass by the molar mass:

Number of moles = 180.0 g / 18.015 g/mol
Number of moles = 9.99 moles

Therefore, there are approximately 10 moles in 180.0 grams of H2O.
