We performed a titration with NaOH solution with KHP. Now I need to calculate the average molarity of NaOH based on this data Weight of khp= 0.1083 g Volume of naoh = 6.4 ml Then if i get this how do i get the molarity of ch3cooh totrated in naoh with the data Volume of vinegar = 1ml Volume of naoh = 8ml
KHP + NaOH ==> NaKP + H2O
mols KHP = grams/molar mass
mols NaOH = mols KHP (from the 1:1 ratio inthe balanced equation.)
M NaOH = mols NaOH/L NaOH.
Withthe vinegar you didn't provide enough data but it's done this way.
mL vn x M vin = mL NaOH x M NaOH.
To calculate the molarity of NaOH, we need to use the data you provided from the titration with KHP (potassium hydrogen phthalate). Here's how you can calculate it step by step:
1. Calculate the number of moles of KHP:
- To do this, we need to know the molar mass of KHP, which is 204.22 g/mol.
- Convert the weight of KHP to moles by dividing it by the molar mass:
Moles of KHP = Weight of KHP / Molar mass of KHP
= 0.1083 g / 204.22 g/mol
2. Calculate the number of moles of NaOH:
- Since KHP and NaOH have a 1:1 stoichiometric ratio, the moles of NaOH will be the same as the moles of KHP.
Moles of NaOH = Moles of KHP
3. Calculate the volume of NaOH in liters:
- Convert the volume of NaOH from milliliters (mL) to liters (L) by dividing it by 1000:
Volume of NaOH (L) = Volume of NaOH (mL) / 1000
= 6.4 mL / 1000
4. Calculate the molarity of NaOH:
- Molarity (M) is defined as moles of solute divided by liters of solution.
Molarity of NaOH = Moles of NaOH / Volume of NaOH (L)
= Moles of KHP / Volume of NaOH (L)
Now that you have calculated the average molarity of NaOH, you can calculate the molarity of acetic acid (CH3COOH) titrated with NaOH using the data you provided:
1. Calculate the number of moles of NaOH:
- Using the volume and molarity of NaOH obtained in the titration with KHP, we can calculate the moles of NaOH.
Moles of NaOH = Molarity of NaOH * Volume of NaOH (L)
2. Calculate the molarity of acetic acid:
- Since acetic acid and NaOH react in a 1:1 stoichiometric ratio, the moles of acetic acid will also be the same as the moles of NaOH.
Molarity of acetic acid = Moles of acetic acid / Volume of acetic acid (L)
To calculate the volume of acetic acid in liters, we need to convert the volume of vinegar from milliliters to liters by dividing by 1000:
Volume of acetic acid (L) = Volume of vinegar (mL) / 1000
With these steps, you can determine the molarity of acetic acid titrated in NaOH with the given volume data.
