Phosphorus pentachloride is produced by the reaction b/w phosphine and chlorine gas.what mass of chlorine gas would be required to produced 0.015kg of phosphorus pentachloride
I solved the problem and I got 20.44g of chlorine gas
2PH3 + 8Cl2 ------> 2PCl5 + 6HCl
0.015kg of PCl5=15g of PCl5
15g of PCl5*(1 mole/208.24 g)=0.07203 moles of PCl5
The reaction shows that 2 moles of PCl5=8 moles of Cl2. So,
0.07203 moles of PCl5*(8 moles of Cl2/2 moles of PCl5)=0.28812 moles of Cl2,
0.28812 moles of Cl2*(70.906 g/moles)=20 g or 0.020kg of Cl2
i got 6.96g of chlorine gas
am i right?
