Can someone please get me started on this one homework question? How many molecules of N2 are in a 500mL container at 780mm Hg and 135 degress Celcius? Thanks David

still need help! The formula my book show for Q=cmdelta T, I guess what I reaaaallllyyy need to know is how to find deltaT given the above problem and then the Lv(latent heat of the unknown substance). This too is a distance learning experience. So please point me in the right direction

I need to determine the latent heat of an unknown substance X in kcal/g if 3.0g of boiling liquid X are completely vaporized in 1.5 hours by an energy source of 10kcal/hr. Thanks a million! Dave
