How much naoh (in mg) is needed to prepare 546 ml of solution with a ph of 10. 00?

Sagot :

2.18 mg of naoh is needed to prepare 546 ml of solution with a ph of 10.00.

What is Molarity?

The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another name for molarity.

We want pOH 4 NaOH solution

Given, pH (10) convert to pOH

pOH = 4; pOH = -log (OH⁻) = 1 x 10⁻⁴ M = NaOH

Once we have got the Molarity = Moles of NaOH/Litre of soln.

Stoich = 1 x 10⁻⁴ M/L X 0.546 L X 40 g NAOh/1 mol

Naoh = 2.18 X 10⁻³ g NaOH = 2.18 mg
