Answer:
It will take 19.03 seconds to effuse Cl2
Step-by-step explanation:
Step 1: Data given
0.15 mol of I2 effuses in 36 sec
Step 2: Calculate the time to effuse 0.15 mol of Cl2
R2/R1 = √(M1/M2)
R = 1/T
T1/T2 = √(M1/M2)
⇒ with T1 = the time needed to effuse I2 = 36 sec
⇒ with T2 = the time needed to effuse Cl2 = TO BE DETERMINED
⇒ with M1 = the molar mass of I2 = 253.8 g/mol
⇒ with M2 = the molar mass of Cl2 = 70.9 g/mol
36/X = √(253.8/70.9)
X= 19.03
It will take 19.03 seconds to effuse Cl2
