Question #a6390
1 Answer
The maximum mass of water that can be produced from your reaction is
So, you're dealing with the combustion reaction of glucose,
Notice the
This means that, regardless of how many moles of glucose react, you'll always need 6 times more moles of oxygen and produce 6 times more moles of water.
So, the first thing to do is determine whether or not you have a limiting reagent, i.e. if one reactant is in insufficient amount compared with the other.
Use glucose and oxygen's molar masses to determine how many moles of each you have
If you go by the number of moles of glucose, the reaction would have needed
SInce you've got more oxygen than the reaction would have needed for that much glucose, glucose will act as a limiting reagent
This means that you'll produce 1.832 micromoles of water, which is equivalent to a mass of
