Elemental analysis is performed on an organic liquid with a fishy odor. Vaporization of 260.0 mg of the compound in a 110 mL bulb at 100°C gives a pressure of 410.0 torr. What is the molar mass of this compound?

Question

whats the formula for this and do I need to convert anything?

Answer 1

Use PV = nRT and solve for n. You must convert 410 torr to atm and 100 C to kelvin.
Then n = grams/molar mass.
You know n and grams. Solve for molar mass.
