Homework Help: Chemistry

Posted by Hannah on Sunday, February 19, 2012 at 5:34pm.

The vapor pressure of diethyl ether is 463.57 mm Hg at 25 degrees celsius. How many grams of aspirin C9H8O4, a non volatile nonelectrolyte (mw=180.1g/mol), must be added to 216.7g of ether to reduce the vapor pressure to 453.74 mm Hg.

Ether=74.12g/mol

This question is similar to the other one that I posted. Do I first have to convert to moles for both?
