One mole of compound A, with vapor pressure 420mmHg at 50°C, mixed with 5 moles of compound B, with vapor pressure 480mmHg at 50°C to form a homogeneous solution. What is the vapor pressure of mixture at 50°C?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
