Interpretation Introduction To determine: The required energy. Explanation Given: The wavelength required is 792 nm . The volume of tube is 100.0 mL . The pressure of iodine is 55.7 mtorr . The temperature is 25.0 ∘ C . The dissociation percentage is 15 .0 % . Explanation: Convert the units of volume as follows: 100.0 mL × ( 1 L 1000 mL ) = 0.1 L Convert the units of pressure as follows: 55.7 mtorr × ( 1 torr 1000 mtorr ) × ( 1 atm 760 torr ) = 7 .33 × 10 − 5 atm Convert the units of temperature as follows: T/K = T/ ° C + 273.15 = ( 25.0 + 273.15 ) K =298 .15 K Calculate the number of moles of iodine present using the ideal gas equation as follows: P V = n R T n = P V R T = ( 7 .33 × 10 − 5 atm ) × ( 0.1 L ) ( 0.082057 L .atm .mol − 1 . K − 1 ) × 298 .15 K = 0 .02996 × 10 − 5 mol Calculate the number of molecules of iodine present as follows: N = 0 .02996 × 10 − 5 mol × ( 6
