1.28 moles of sodium hydroxide are in the solution.
Number of moles- The ratio of a substance's given mass in a chemical reaction to the mass of one mole of that material is the number of moles of that substance. A mole of any substance is equal to 6.023 ×10²³, or Avogadro's number. Additionally, it is employed to express concentration measurements like mole per litre and molecular weight.
Given-
The solution's molarity is 0.450 M.
The solution's volume is 350 mL or 0.35 L.
Calculating the number of moles:
We are aware of the following molarity formula:
M = nV (where n is the number of moles and V is the volume in Liters)
swapping out the variables
⇒ 0.450 = n × (0.35)
⇒ n = 0.450 / 0.35
⇒ n =1.28 moles
As a result, the given solution contains 1.28 moles of Na(OH).
