1) We have assumed that the unknown does not dissociate into more than one particle when dissolved. If this was an incorrect assumption and the solid did dissociate slightly. Then how would the calculated molar mass of solute from our experiment differ from the actual molar mass? The calculated would be (too high, too low or unaffected) compared to the actual? Explain briefly. 2)If you measured the experimental freezing point of 30g cyclohexane with 0.012mols of Toluene (MWT= 92.15) and...

Two students in a physics laboratory each have a concave mirror with the same radius of curvature, 50.0 cm. Each student places an object in front of a mirror. The image in both mirrors is three times the size of the object. However, when the students compare notes, they find that the object distances are not the same. What is the distance of the farther object?
