Problem on weight fraction
A gas contains 350 ppm of H2S in CO2 at 72°F and 1.53 atm pressure. If the gas is liquified, what is the weight fraction H2S?

Now we consider 1liter of CO2 at 72deg F {[K] ≡ (72+ 459.67) × 5/9}=295.3722 K 1.53 atm
So No moles n= PV/RT =1.53atm*1liter/(0.08205liter-atm/K-mole*295.3722) =0.063131mole
So wt of CO = 0.063131mole*28g/mole =1.76767g
Now 350 ppm H2S would have a volume 350 microlitre ( µL ) per litre, = 350 ppm =350E-6 litre
So No of moles H2S = n= PV/RT =1.53atm*(350E-6)liter/(0.08205liter-atm/K-mole*295.3722K) = 2.20959E-05 mole
The MW H2S = 34.116g/mole
So wt of H2S = 0.000753823 g
So total weight =1.768423823g
So %wt H2S = (0.0007538236/1.768423823g)*100%=0.04262%
Modeling eye movements is commonly performed in the Matlab/Simulink pacakage. Based on the Physiological evidence, oculomotor plants have been designed to simulate various eye movements. Choose two eye movement models, one for saccades and the other for pursuit, and simulate the following amplitudes

The Clausius-Clapeyron equation gives us an expression for dP/dT. Now we will derive an analog to the Clausius-Clapeyron equation by obtaining an expression for dT/dµ when two phases are at equilibrium. For simplicity, let’s derive this fo
