Asample of nitrogen has a volume of 50.0l at a pressure of 760mmhg. what is the volume of the gas at each of the following pressures if there is no change in temperature?
a. 1500mmhg b. 4.00 atm c. 0.500atm

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
