The formula mass of sodium hydroxide, NaOH is 23.0+16.0+1.0=40.0
Amount of NaOH in 25.0g sample = 0.625mol
Since NaOH is a strong base, one mole (6.022x1023) of Na+ ions are formed when one mole of NaOH dissolves in water.
2 moles of NaOH will react with 1 mole of H2SO4 based on the balanced chemical equation: 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
These chemicals react in a direct proportion of one to one, measured in moles of course, not by weight. A mole of NaOH weighs more than a mole of HCl.
There are a total of 5 atoms in 2 NaOH (sodium hydroxide) - 2 sodium atoms, 2 oxygen atoms, and 1 hydrogen atom in each molecule.
Grams NaOH?? Balanced equation. 2NaOH + H2SO4 --> Na2SO4 + 2H2O 4.9 grams H2SO4 (1 mole H2SO4/98.086 grams)(2 mole NaOH/1 mole H2SO4)(39.998 grams/1 mole NaOH) = 4.0 grams NaOH needed =================
Since NaOH is a strong base, one mole (6.022x1023) of Na+ ions are formed when one mole of NaOH dissolves in water.
This is acetic acid which is monobasic acid so one mole of it is neutralized by one mole of NaOH.
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
2 moles of NaOH will react with 1 mole of H2SO4 based on the balanced chemical equation: 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
No, they are not. "0.5 mole of NaOH" means that you have half a mole of sodium hydroxide. "0.5M of NaOH" means that you have half a mole of sodium hydroxide for every liter of solution. "0.5M" is also commonly written as "0.5 mol/L" or "mol L-1".

When titrating NaOH with KHP (potassium hydrogen phthalate), the number of moles of NaOH will be equal to the number of moles of KHP at the equivalence point. This is because the reaction is stoichiometric, with one mole of NaOH reacting with one mole of KHP.
One mole of sodium hydroxide (NaOH) releases one mole of sodium ions (Na+) when dissolved in water. This is because each formula unit of NaOH contains one sodium ion.
17.32 moles H2O (2 moles H/1 mole H2O) = 34.64 moles hydrogen
There is one hydrogen atom in one formula unit of NaOH.
