Asample of 02 gas occupies 346 ml at 45°c and 1.50 atm. what is the volume of this o2 gas sample at stp? enter your answer in the provided box. l l

Explanation:

The given data is as follows.

      = 346 mL,     = = (45 + 273) K = 318 K,

      = 1.50 atm,    = ?,   = 273 K,

      = 1 atm

And, according to ideal gas equation,

Now, putting the given values into the above formula and we will calculate the final volume as follows.

            = 445.56 mL

Thus, we can conclude that the volume of this gas sample at STP is 445.56 mL.

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.
