What is the volume of a pure silver coin that has a mass of 14 g? the density of ag is 10.5 g/ cm3?

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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.
