Which of the following is a true statement? A. If one mole of 39K has a mass of 39.1 grams, the mass of one atom of 39K is 39.1x10^-23 grams.
В. If one atom of 12C has a mass of 12.0 amu, one mole of 12C atoms has a mass of 12 x 6.02x10^23 grams.
C. If one atom of 223Fr has a mass of 223.0 amu, one mole of 223Fr has a mass of 223.0x10^23 amu.
D. If one atom of 1271 has a mass of 126.9 amu, one mole of 1271 has a mass of 126.9 grams.

its going to be mutualism cuz they both benefit from the relationship.

here's the link to your question!

explanation:

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.

what is the question?
