1. Find the molar mass of water (H₂O):
* Hydrogen (H) has a molar mass of approximately 1 g/mol.
* Oxygen (O) has a molar mass of approximately 16 g/mol.
* Molar mass of water = (2 * 1 g/mol) + 16 g/mol = 18 g/mol
2. Use the formula:
* grams = moles * molar mass
3. Substitute the values:
* grams = 1.57 moles * 18 g/mol
* grams = 28.26 g
Therefore, there are approximately 28.26 grams in 1.57 moles of water.
