What is a mole ratio example?
- A chemical reaction's molar ratio is the ratio of the moles (or molecules) of reactants used and the moles (or molecules) of products produced.
- Two moles of H2O are produced for every mole of O2 that is utilized. H2 and H2O have a mole ratio of 1:1. Two moles of H2 are needed to create two moles of H2O. Four moles of hydrogen would be required to make four moles of water.
- The ratio between any two compounds in a chemical reaction is known as the mole ratio. It is the proportion between two coefficients in a chemical equation that is balanced. Mole-to-mole ratio and molar ratio are other names for the mole ratio.
- Use the atomic masses to translate each element's mass into moles. By dividing the total number of moles by the smallest number of moles, you may determine the ratio or the number of moles of each element.
Using the Henderson-Hasselbalch equation,
pH pKa log
pH 4.76 log ([acetate]/[acetic acid]), where [acetate]/[acetic acid] is the ratio given for each part of the question.
pH = pka + log [acetate/acetic acid]
pH = 4.76 + log ( 5/1)
pH = 5.46
