Balance the equation.
Then get the number of moles.
Time to use mole ratio,
Converting to grams from moles.
Stoichiometry, an equation to you.
Stoichiometry, an equation to you.
H2 + O2 forms
H20. Yeah, there's your
Unbalanced equation.
Add some coefficients.
Chorus
Get 2H2 + O2
To form 2 H2O.
Now how much of H2O
Is made from 10 grams of H2?
Chorus
Moles are grams over MM.
Ten grams become 5 moles.
Take the known over unknown.
H2 over H2O.
Chorus
You get five over X
Equals 2 over 2.
That's five moles of H2O.
Convert that back to grams.
Chorus
Follow the 4step plan.
Stoichiometry.
How much product is produced?
Use the ratio, you'll see.
Chorus
