Answer 3

Well all you need to do is multiply the number of moles times the heat of vaporization for water.

\[0.75~grams*(\frac{ mol }{ 18grams })*(40.79*10^{3}J/mole) = energy~total\]

Answer 4

oh

Answer 5

did i mess up number 2?

Answer 6

its number 2 the same as number 1 but just a little different

Answer 7

didnt i do number 2 right?

Answer 9

i think he is AFK

Answer 10

lol

Answer 11

I can't understand what you wrote at the end

Answer 12

But, you set it up correctly. I just converted mine to joules.

Answer 13

oh how would u do number 3?

Answer 14

pretty sure you can set up a ratio you need to first find the molar mass of that compound.

Answer 15

because remember, the hint here is molar enthalpy of vaporization. then i will continue to guide you.

Answer 16

yeah idk how to set it up

Answer 17

wait i will try first
