Hydrogen and oxygen react to form water as shown in the reaction below. A mass of 7.2 grams of hydrogen is allowed to react completely with excess oxygen. However, the percent yield for this reaction is calculated to be only 90%, possibility due to an unknown experimental error. How many grams of water were actually formed in this reaction? (Please give your answer to 1 decimal place.)
H2 + O2 --> H2O
