Problem: Chlorine is widely used to purify municipal water supplies and to treat swimming pool water. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 895 torr and 24 oC.What volume will the Cl2 occupy at STP?

FREE Expert Solution

Step 1

PV = nRTPV = mMMRTm = PV×MMRTm = (895 torr×1 atm760 torr)(8.70 L)(70.9 gmol)(0.08206 atm·Lmol·K)(24°C + 273.15)K
