2) As NASA's Chief Chemist you are told to supply enough water for one astronaut for 2 days. Water is not carried on board the Shuttle. It is made when hydrogen and oxygen react together in a fuel cell<b><i>fuel cell</i></b> to produce electrical energy.
The byproduct of this reaction is life sustaining water. An astronaut requires 2.7kg of water per day. How much hydrogen and oxygen will you need to have on baord to maintain the water requirements for one astronaut over the two day mission?

grams of oxygen gas

grams of hydrogen gas
