Homework Help: chemistry

Posted by Jim_R on Thursday, July 16, 2009 at 7:35pm.

ok im not sure how to do this

15.00ml of acetic acid is pipetted into a flask

0.35 grams of sodium acetate trihydrate is added and mixed

then 0.75 of the hydrate is added

1)i assumed that the volume(s) are additions. 15.00ml x .35g *m/1.45g and for the second part 15.00 + 0.35g *mol/1.45 g +0.75 g* mol/1.45g= x

2)not sure how to do the tryhydate. Do i minus it from the total mass of sodium hydrate ? or is it non reactive?

can u show me the proper method to do this ?
