Write the complete solution in short and simple way
sodium nitrate was added to 2.0 l of water at 25 degc to produce a saturated solution. the solution was then heated to
The freezing point for t-butanol is 25.50 degrees C and kf is 9.1 degrees C/m. Usually t-butanol absorbs water on exposure to the air. If the freezing point of a 10.0 g sample of t-butanol is measured as 24.59 degrees C, how many grams of water ar..
