How many grams of NaOH are in 250 mL of a 3.0M NaOH solution?

Sagot :

Data:

Solute = NaOH

Volume of solution = 250 mL => (1 L = 1000 mL) => 250 mL = 0.250 L

Concentration = 3.0 M (mol/L)

-------------

Please, look up the molar mass of NaOH => 40 g/mol approx.

-------------

We will work with the next formula:

Molarity = moles of NaOH/volume of the solution (L)

Clear the moles of NaOH:

Molarity x volume = moles

3.0 mol/L x 0.250 L =
