# By measuring the equilibrium between liquid and vapour phases of an acetone(a)/methanol(m) solution

By measuring the equilibrium between liquid and vapour phases of an acetone(a)/methanol(m) solution at 57.2°c at 1.00 atm, it was found that xa = 0.400 when ya = 0.516. calculate the activities and activity coefficients of both components in this solution on the raoult’s law basis. the vapour pressures of the pure components at this temperature are: p*a = 105 kpa and p*m = 73.5 kpa. (xa is the mole fraction in the liquid and ya the mole fraction in the vapour.)

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
