Which of the following is the number of moles of a solute that is dissolved in 1 liter of solution? A. mass percent B. molality
C. molarity
D. mole fraction​

B. molarity

Explanation:

The molarity of a solution is the number of moles of solute dissolved in one liter of solution.

B. Molarity

Molarity is the number of moles of solute present in one litre of the solution.

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.

b.

the accuracy of the data.
