Web12 jan. 2024 · Prepare 2 M sodium hydroxide Prepare 10% sodium hydroxide Normality Equation: The equation for normality is easy to understand if you have understood the gram equivalent weight. Normality (N) = m /V × 1 / Eq m is mass of solute in grams V is total volume of solution in Liters Eq is equivalent weight Normality calculation of NaOH: Web5 dec. 2014 · You correctly converted 500 mL to 0.5 L. Now, we can put the information we already have into the formula. We want a solution with 0.1 M. So, we will do 0.1=x/0.5; 0.1*0.5. Solving for x, we find that we need 0.05 moles of solute NaOH. As you found, the molar mass of NaOH is 40 g. So, we will do 40 g*0.05, which is about 2 g. sympathy box idea
