To calculate the number of moles use the following formula: n = m / rmm
The rmm for sodium hydroxide is (Na: 22.99 x 1) + (O: 15.99 x 1) + (H: 1 x 1) = 39.98 g / mol.
So... n = 67.23 g / 39.98 g / mol
= 1.68159 mol
The number of moles of NaOH used in the titration process can be calculated by dividing the volume of NaOH solution used by the molarity of the NaOH solution.
1st Get the balanced equation NaOH + HCl -> NaCl + H2O Find the number of moles in HCl; n = cv n = 0.46x0.61 n = 0.2806 moles the number of moles of HCl and NaOH is the same so 0.2806moles will be needed
When titrating NaOH with KHP (potassium hydrogen phthalate), the number of moles of NaOH will be equal to the number of moles of KHP at the equivalence point. This is because the reaction is stoichiometric, with one mole of NaOH reacting with one mole of KHP.
The number of moles is 0,0038.
To find the number of moles of NaOH, you need to divide the given number of formula units by Avogadro's number (6.022 x 10^23). Therefore, the number of moles of NaOH is 10.84/6.022 ≈ 1.8 x 10^-23 moles.
To calculate the grams of NaOH in the solution, you first need to find the moles of NaOH present in 400.0 ml of the solution. The moles of NaOH can be calculated using the formula: moles = molarity x volume (in liters). Once you have the moles of NaOH, you can then calculate the grams using the formula: grams = moles x molecular weight.
I believe the molarity is 1. molarity = number of moles / liters of solution molarity = 3 / 3 = 1
Molarity = moles of solute/Liters of solution (18.00 ml = 0.018 Liters)0.1123 M NaOH = X moles solute/0.018 L= 2.021 X 10 -3 moles NaOH============================as all is one to one,2.021 X 10 -3 moles OH -==================
Need moles sodium hydroxide first.80 grams NaOH (1 mole NaOH/39.998 grams) = 2.000 moles NaOHMolarity = moles of solute/Liters of solutionMolality = 2.000 moles NaOH/1 liter= 2 M NaOH solution===============
2.2 moles of NaOH weigh 99.55 grams. This is calculated by multiplying the number of moles by the molar mass of NaOH, which is 40 grams per mole for Na (22.99 g/mol) + O (16.00 g/mol) + H (1.01 g/mol).
First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0.45 L Moles = 0.25 N x 0.45 L = 0.1125 moles of NaOH.
To find the number of moles of NaOH, first convert the volume from mL to L (16.5 mL = 0.0165 L). Then, use the formula moles = concentration (mol/L) × volume (L) to calculate the moles of NaOH. Plugging in the values: 0.750 mol/L × 0.0165 L = 0.0124 moles of NaOH.
