What is the mass of one molecule of water?
Understand the Problem
The question is asking to determine the mass of a single molecule of water by looking at its molecular formula and calculating its molar mass, then dividing it by Avogadro's number.
Answer
2.99 x 10^-23 grams
The mass of one molecule of water is approximately 2.99 x 10^-23 grams.
Answer for screen readers
The mass of one molecule of water is approximately 2.99 x 10^-23 grams.
More Information
The molar mass of water is 18.01 g/mol, and Avogadro's number is 6.022 x 10^23 molecules/mol. Using these, you divide 18.01 g/mol by 6.022 x 10^23 molecules/mol to get approximately 2.99 x 10^-23 grams for a single water molecule.
