Title: Stoichiometry - how many grams of water will be formed?
Post by: GPCR pathway on January 17, 2019, 05:21:11 AM
An electric spark is passed through a mixture of 12 grams of hydrogen gas and 24 grams of oxygen gas in an enclosed tube. In the completion of the reaction, how many grams of water will be formed?

Already found that the limiting reagent is Oxygen with 0.75 mol (?)

What are the next steps?

How many mole H2 correspondend to 0,75 mol O2.  The how many mole corresponded to that value. Convert this to the mass.
