How many grams of h2o will be formed when 32.0 g h2 is mixed with 32.0 g o2 and allowed to react to form water?

*Given
  Mass of hydrogen ()  -  32.0 grams
  Mass of oxygen ()     -  32.0 grams

*Additional Information 
  Molar mass of hydrogen () - 2.00 g/mol
  Molar mass of oxygen ()    - 32.00 g/mol
  Molar mass of water ()    - 18.00 g/mol
 
Chemical Reaction:
                    
   +     -------->
                                  
*Solution

From the chemical reaction above, we can see that for every 1 molecule or mole of oxygen (), we would need 2 molecules or moles of hydrogen () to form water ().
