It is 25 moles of Sodium Hydroxide (;
the molar mass of sodium hydroxide is 40g/mol mike
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.

To make a 5% water solution of sodium hydroxide, you would mix 5 grams of sodium hydroxide with 95 grams of water. This will give you a total of 100 grams of solution, with 5% of it being sodium hydroxide. Remember to always add the sodium hydroxide to the water slowly and with caution due to its caustic nature.

how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams per mole.

The iron(III) hydroxide is not soluble in water and doesn't react with sodium chloride.
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
To find the amount of sodium hydroxide needed to react with 150g of phosphoric acid, you first need to determine the balanced chemical equation between sodium hydroxide and phosphoric acid. From there, you can use stoichiometry to calculate the amount of sodium hydroxide needed.
