At 60 c the vapor pressure of benzene is 386 torr and that of toluene is 133 torr. A liquid mixture is made by combining 1.10 mol of toluene with 2.40 mol of benzene. It is in equilibrium with a vapor. Find the mole fraction of toluene (a) in the liquid and (b) in the vapor. I dont need to know the answer more just the steps needed to find the answer. If you have a different example you can explain that would be great! Im just trying to learn chemistry!!

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

it would be a gas formation
