Moles of "Cl_2=\\frac{25}{71}=0.352"
Moles of "F_2=\\frac{10}{19}=0.526"
Total moles"(n)=0.526+0.352=0.878"
"T=25\\degree C=298K"
Using ideal gas equation,"PV=nRT\\implies P\\times 8=0.878\\times 0.0821\\times 298\\implies""P=2.685\\ atm"
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
