The boiling point of benzene, C6H6 is 80.10 °C at 1 atmosphere and its Kbp value is 2.53 °C/m. A nonvolatile, nonelectrolyte that dissolves in benzene is testosterone . How many grams of testosterone, C19H28O2 (288.4 g/mol), must be dissolved in 264.0 grams of benzene to raise the boiling point by 0.300 °C?
You add 0.230 g of an orange, crystalline compound whose empirical formula is C H,Fe to 10.70 g of benzene. The boiling point of the benzene rises from 80.10 °C to 80.25 °C. What are the molar mass and molecular formula of the compound? Kbp for benzene is +2.53 "C/m.) Molar mass = g/mol Molecular formula:

(4 Points) Gasoline is primarily a mixture of hydrocarbons and is sold with an octane rating that is based on a comparison with the properties of isooctane (CsHis), which has an enthalpy of vaporization of 35.8 kJ/mol and a normal boiling point of 98.2 °C. Determine the vapor pressure of isooctane on a very hot day when the temperature is 38.0 °C. 1. (4 Points) A 15.0 mg sample of a protein was dissolved in water to produce 5.00 mL...
