How many grams of diazine (N2H2) are there in 2.55 mol of the compound

76.5g is present in 2.55mol of diazine

Explanation:

no. of mole equals mass over molar mass

molar mass of diazine equals 30g/mol.. then substitute to get the mass in grams which is 76.5g

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.
