Consider the balanced equation below what is the mole ratio of pcl3 to pcl5 11 21 35 53


In order to determine the mole ratio of two compounds in a balanced equation, one must first determine the molar mass of each individual compound. This can be done by adding up the atomic masses of each element in the compound. For example, the molar mass of chlorine is 35.5 g/mol, so in order to find the molar mass of sodium chloride, or NaCl, we would add 23 + 35.5 to get 58.5 g/mol. Once we have determined the molar mass of each compound, we can then use the coefficients from the balanced equation to find the mole ratio. In our sodium chloride example, there is a 1:1 mole ratio of Na to Cl. This means that for every mole of sodium there is also one mole of chlorine.

What is the mole ratio of pcl3 to pcl5?

In order to determine the mole ratio of pcl3 to pcl5, we need to first identify the molar masses of each substance. The molar mass of pcl3 is 303.33 g/mol and the molar mass of pcl5 is 505.55 g/mol. This means that there are 1.68 mol of pcl3 for every mol of pcl5. Therefore, the mole ratio of pcl3 to pcl5 is 1.68:1.

How to calculate the mole ratio of pcl3 to pcl5

In stoichiometry, the mole ratio is the ratio of two quantities of moles. In other words, it is a fraction that represents the number of moles of one compound in relation to the number of moles of another compound. The mole ratio can be used to convert between moles and mass, or between different compounds.

To calculate the mole ratio, you need to know the balanced chemical equation for the reaction. In the equation, each compound is represented by its chemical formula and a number. The number is called the stoichiometric coefficient and it tells you how many molecules (or moles) of that compound are involved in the reaction.

For example, consider the following balanced equation:
2 H2 + O2 –> 2 H2O

In this equation, there are two molecules (or moles) of hydrogen gas for every molecule (or mole) of oxygen gas that reacts. This means that the mole ratio of H2 to O2 is 2:1. Alternatively, you could say that for every two moles of hydrogen gas, there is one mole of oxygen gas.


PCL3 and PCL5 react in a 1:1 molar ratio, meaning that for every mole of PCL3 that reacts, one mole of PCL5 is produced.
