If 10 mols of Hydrogen gas was available to react with excess Oxygen, how many grams of water would be produced? 2H_(2)+O_(2)otimes 2H_(2)O 180 g 90.0 g 3.6 g 45.0 g

## Step1: Determine the Molar Mass of Water### Calculate the molar mass of water ( ) by adding the atomic masses of its constituent elements: for hydrogen and for oxygen, resulting in .## Step2: Use Stoichiometry to Find Moles of Water Produced### According to the balanced chemical equation , 2 moles of produce 2 moles of . Therefore, 10 moles of will produce 10 moles of .## Step3: Convert Moles of Water to Grams### Multiply the moles of water (10 moles) by the molar mass of water (18.02 g/mol) to find the mass of water produced: .
