A solution is prepared by mixing 25 mL pentane (C3H12, d =
0.63 g/cm) with 45 mL hexane (C6H14, d = 0.66 g/cmº).
Assuming that the volumes add on mixing, calculate the mass
percent, mole fraction, molality, and molarity of the pentane.

What is a main difference between a mixture and a pure substance? a mixture is only a liquid, but a pure substance can be in any state.a mixture looks the same throughout, but a pure substance does not.1 a mixture can vary in composition, but a pure substance has a set composlo a mixture can be made up of a single compound, but a pure substance car
