How much Cu is produced in the equation CuO + H2 = Cu + H2O when 13.6 g of CuO are exposed to 2.42g of H2?

the millers tale is the answer.

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.
