A chemist prepares a mixture of hexane and toluene at a temperature of 21.0 °C. He measures out 314. mL of hexane and mixes it with 0.74 L of toluene. He measures the volume of the solution after it is well mixed and finds that it is 1.03 L. The density of hexane is 0.66 g/mL and the density of toluene is 0.87 g/mL. Calculate the volume percent of hexane in this solution. Be sure your answer has the right number of significant digits. ?

Explanation
A chemist prepares a mixture of hexane and toluene at a temperature of 21.0 °C. He measures out 314. mL of hexane and mixes it with 0.74
L of toluene. He measures the volume of the solution after it is well mixed and finds that it is 1.03 L. The density of hexane is 0.66 g/mL and
the density of toluene is 0.87 g/mL.
