the mass of sample X is 20.0 g. It was placed in a graduated cylinder and the water level rose from 14mL to 19mL. what is the density of sample X? Pay close attention to significant figures

the answer your looking for is c).

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
