Problem

Determine the volume of hexane that contains 5.33 x 10 22 molecules of hexane. The density of hexane is 0.6548 g/mL and its molar mass is 86.17 g/mol. 

a. 13.5 mL

b. 12.4 mL

c. 11.6 mL

d. 8.59 mL

e. 7.40 mL

Solution

For this problem, we’re being asked to determine the volume of hexane found in 5.33 x 10 22 molecules of hexane


The flow for this problem will be like this:


molecules of hexane (Avogadro’s number)  Moles of hexane (molar mass of hexane)  mass of hexane  (Density) volume hexane
