To find the mass of 0.55 moles of C6H6 (benzene), first calculate its molar mass. The molar mass of C6H6 is approximately 78.11 g/mol (6 carbon atoms at about 12.01 g/mol each and 6 hydrogen atoms at about 1.01 g/mol each). Multiplying the number of moles by the molar mass, the mass of 0.55 moles of C6H6 is about 42.96 grams.

A solution contains 72.0 g of HCl and 468 g of (C6H6). What is the mole fraction of benzene?
First, calculate the moles of each component: moles of HCl = 72.0 g / molar mass of HCl and moles of C6H6 = 468 g / molar mass of C6H6. Then, calculate the total moles in the solution by adding the moles of each component. Finally, calculate the mole fraction of benzene by dividing the moles of C6H6 by the total moles in the solution.
