A chemist boils off the water from 627 mL of a solution with a pH of 10.2. The only dissolved compound in the solution is NaOH. How much solid remains?
To determine the mass of the NaOH that remains, you can use the pH to determine the concentration of OH- ions. From there, you can calculate the moles of NaOH you started with using the concentration and the volume of the solution. Then, you can use the molar mass to calculate the mass of NaOH remaining which would be 0.00403 g.

Since the liver is responsible for ridding your body of toxic substances, liver cells likely would have a lot of smooth ER an organelle responsible for purifying toxins.
