Chemistry 2 boiling point Very Urgent !!!!!!!!!
« on: November 27, 2010, 11:14:38 PM »
Could someone in detail tell me how to do this? Then I'll be able to pass this test.

Compute the boiling point of 25.5 g of C7H11NO7S (4-nitro-2-toluenesulfonic acid dihydrate) in 1.00 x 10^2 gH2O (nonionizing solute)

Please as much detail as possible.

I got 253 for the mass of 4-nitro-2-toluenesulfonic acid dihydrate

Then you have to multiply by 0.512

I dont know about the rest im lost.

Do you know what boiling point elevation is? Ebullioscopic constant? If not, check.
