how many grams of sodium hydroxide are required to dissolve in 232 g of water to make a 2.88 m solution

Grams of Sodium hydroxide : 26.72 g

Molality shows the number of moles dissolved in every 1000 grams of solvent.

m = n. (1000 / p)

m = Molality

n = Number of moles of solute

p = Solvent mass (gram)

Can be written :

m=2.88

kg solvent(water)=232 g=0.232 kg

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.
