The vapor pressure of 0.388 g of a pure substance is 0.631 atm at 20degree celcius (the molar mass of this substance is 124.83g/mol). If the addition of glucose lowers the vapor pressure to 0.555atm, how many moles of glucose are present in solution?
The common laboratory solvent ethanol is often used to purify substances dissolved in it. The vapor pressure of ethanol, CH3CH2OH, is 54.68 mm Hg at 25 °C. The molecular weight of ethanol, CH3CH2OH, is 46.07 g/mol.
In a laboratory experiment, students synthesized a new compound and found that when 26.79 grams of the compound were dissolved in 150.7 grams of ethanol, the vapor pressure of the solution was 53.17 mm Hg. The compound was also found to be nonvolatile and a nonelectrolyte.
What is the molecular weight of this compound?
