Remember that mass changes only occur because a gas is being released into the atmosphere or because a gas from the atmosphere is being used as a reactant -no atoms are created or destroyed only rearranged :-)
Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.
The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.
A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.
A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.
According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.
A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.
From the information provided;
Number of moles of acid = 0.002 moles
Volume of solution= 2 L
Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M
pH = - log[H^+]
pH = - log[0.001 ]
pH = 3
From;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 8.5
pOH = 5.5
pOH = - log[OH^-]
[OH^-] = Antilog[-5.5]
[OH^-] = 3.2 × 10^-6 M

Answer:
Ok, so the goal of a titration is to figure out the concentration of the NaOH solution by seeing how much acid it takes to neutralize the NaOH solution. NaOH is a base, you want to neutralize it with an acid. The best acids to use would be a strong acid.
Some good choices would be hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid, nitric acid, or sulfuric acid. In reality, though, you could use pretty much any acid you wanted to.
Oh, and you should probably also add an indicator to your solution so that you know when your titration is done. In this case, a good choice would be phenolphthalein because it changes color right about pH of 8.

70 because the lemonade is not that heavy and it’s just right in the middle
