A cyclopropane gas mixture can be used as an anaesthetic. Suppose a container of 10.0 L volume is held at 30.0 oC and a mixture is formed by placing 5.08 g of cyclopropane (C3H6) and 10.5 g of oxygen gas into the previously empty container. Using the information above, determine the mole fraction of oxygen.

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.
