What is the relationship between Molar concentration and stoichiometric mole ratio?
They are proportional to the number of reactants consumed in the reaction. Yes. The concentrations of the two solutions must be the same in order for the stoichiometric mole ratio of the reactants to be accurate after the results of the trial are graphed because molar concentration is moles of solute divided by liter of solution.
What is the best way to find the experimental molar ratio of a compound?
If the question had been stated in terms of grams, you would have had to convert grams of H₂O to moles of H₂O, then moles of H₂O to moles of O₂ (as above), and finally moles of O₂ to grams of O₂. To get the experimental molar ratio, you divide the moles of each reactant that you actually used in the experiment by each other.
What is the mole ratio of a substance and why is it important?
Example: 2 H 2 + O2 ===> 2 H 2O the H 2: O2 mole ratio is 2:1 and the H 2: H 2O mole ratio is 2:2 or 1:1. The mole ratio is used to help convert from one substance to another, especially for changing grams of A to grams of B. Combined with molar mass the mole ratio is a very powerful tool.
What is the mole ratio of the reaction between H2O and O2?
For the reaction: 2 H 2(g) + O 2(g) → 2 H 2O(g) The mole ratio between O 2 and H 2O is 1:2. For every 1 mole of O 2 used, 2 moles of H 2O are formed. The mole ratio between H 2 and H 2O is 1:1. For every 2 moles of H 2 used, 2 moles of H 2O are formed.
