If a sample of oxygen occupies a volume of 2.15 l at a pressure of 58.0 kpa and a temperature of 25°c what volume of the sample a company at 101.3 k pa and 0°c

1.13 L

Explanation:

Given data

We can find the final volume of the oxygen gas using the combined gas law.

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.
