What is the mole ratio between NaCl and Na?
The ratio of moles of Na to moles of Cl2 is 2:1, but the ratio of moles of Na to moles of NaCl is 2:2, and the ratio of moles of Cl2 to moles of NaCl is 1:2. These mole ratios can be developed for any balanced equation and can be used to determine how much product is made from a given amount of starting material.
How do you find mole ratio?
Once you know the number of moles of each component of the compound, you divide each by the one with the lowest number and round to the nearest integer. The numbers are the mole ratios, and they appear as subscripts in the empirical formula.
How are mole ratios used in chemical calculations?
In chemical calculations, mole ratios are used to convert between moles of reactant and moles of product, between moles of reactants, or between moles of products. … Then the mole ratio from the balanced equation is used to calculate the number of moles of the wanted substance.
