A solution contains a mixture of substance A and substance B, both of which are volatile. The mole fraction of substance A is 0.162. At 27oC, the vapor pressure of pure A is 129. mm Hg and the vapor pressure of pure B is 209. mm Hg. Determine the total vapor pressure (mm Hg) of the solution at this temperature

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
