How many moles are in 4.75 g of sodium hydroxide?

4.75 g of NaOH (1.19 x 101 mol NaOH) Answer: The molar mass of NaOH was solve in section A to be 40 g/mol.

How do you find the moles of NaOH?

Step 1: Calculate the amount of sodium hydroxide in moles

  1. Amount of solute in mol = concentration in mol/dm 3 × volume in dm 3
  2. Amount of sodium hydroxide = 0.100 × 0.0250.
  3. = 0.00250 mol.
  4. The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
  5. So the mole ratio NaOH:HCl is 1:1.
