Answer to Problem 21LC
Mole ratios are used in chemical calculations to convert moles of reactant or product to different moles of reactant or product.
Explanation of Solution
Consider a balanced chemical equation:
In this reaction, two moles of hydrogen react with one mole of oxygen to give two moles of water.
A mole ratio conversion for the balanced chemical equation can be written as:
So, this is how mole ratio conversion can be done in calculations.
