I NEED HELP ASAPPP Two amounts of the same element, no matter their mass, will have the same density.

True or false?

True

Explanation:

If it is the same element no matter the volume the density will be the same. Since both are the same substance, as long as both were in the same temperature and phase their density will be identical.

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.

your answer would be “dry”
