First, find the molar mass of H2O. It may vary depending on your source. Use the source your teacher gave you.

I got 18.015 g/mol as the molar mass of water.

Then you basically do some math to figure out the amount of moles ...

9.15 grams * (1 mole H2O) / (18.015 grams H2O) =.5079

There is approximately. 51 moles present.
