Asked by Rebekah
In the explosion of a hydrogen-filled balloon, 0.75 g of hydrogen reacted with 6.9 g of oxygen to form how many grams of water vapor? (Water vapor is the only product.)
I am really confused on how to do this.

H2+O2->H2O
balance the equation:
2H2+O2->2H2O
now using the balance equation, find how many grams of water vapor is formed? (hint: this is a limiting agent problem)
-find number of grams of H2O produced from .75g H2
-find number of grams of H2O produced from 6.9g O2
-which number is smaller? (that's the limiting reagent & that's how many grams of water vapor form!)
