The common laboratory solvent water is often used to purify substances dissolved in it. The vapor pressure of water is 23.76 mm Hg at 25 °C. In a laboratory experiment, students synthesized a new compound and found that when 16.06 grams of the compound were dissolved in 292.4 grams of water, the vapor pressure of the solution was 23.38 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this compound? (Water = H₂O 18.02 g/mol) Molecular weight = 15.79 g/mol

The common laboratory solvent water is often used to purify substances dissolved in it. The vapor pressure of water is 23.76 mm Hg at
25 °C.
In a laboratory experiment, students synthesized a new compound and found that when 16.06 grams of the compound were dissolved
in 292.4 grams of water, the vapor pressure of the solution was 23.38 mm Hg. The compound was also found to be nonvolatile and a
non-electrolyte.
What is the molecular weight of this compound?
(Water = H₂O = 18.02 g/mol)
Molecular weight = 15.79 g/mol
