How many cubic cm^3 would be present in a space that is 5.00 in x 4.00 in x 7.00 in?

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
