A mixture of helium and xenon gases contains helium at a partial pressure of 303 mmHg and xenon at a partial pressure of 655 mmHg. What is the mole fraction of each gas in the mixture?
Tfe common taboratory solvent ethanol is often used to purify substances dissolved in it. The vapor pressure In a laboratory experiment, students synthesized a new compound and found that when 30.20 grams of the compound were dissolved in 293.8 grams of ethanol, the vapor pressure of the solution was 53.30 mm. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this compound?  (Ethanol =CH3​CH2​OH=46.07 g/mol )  Molecular weight = 9/mol
