The following article will add knowledge about “What mass of pcl5 will be produced from the given masses of both reactants?“. Let’s keep an eye on the content below!
What mass of PCl5 will be produced from the given masses of both reactants?
- 28.0 g of P4
- 59.0 g of Cl2
Answer
We are told this from the question. Which mass of PCl5 can be made from the reactants’ masses? 28.0 g of P4 & 59.0 g of Cl2
Explanation
The chemical formula for reactants and products is called the reaction equation.
The chemical formula for a substance is known as the reaction coefficient. It is the number that represents the chemical reaction equation. It is used to equalize reactants and products.
The equation for reaction can generally be described mathematically as
P4 + 10Cl2 – – – – – –4PCl5
Therefore
No of moles P4= 28/124
No of moles P4=0.225moles
No of moles of Cl2=59/71
No of moles of Cl2=0.831 moles
0.831 mole of Cl2=0.0.831 moles of P4 & produce 0.3324 moles PCl5
Therefore
Mass a PCl5 =moles of PCl5 * modar mass PCl5
molar mass PCl₅= 208.5
Mass a PCl5 = 0.3324 * 208.5
Mass a PCl5 = 69.3 g
As we can see, the question states that the mass of PCl5 is produced from the respective masses of the reactants.
Mass a PCl5 = 69.3g
