If 2% sulphur is to be doped using thiourea as a precursor in TiO2 (using titanium butoxide as a precursor), What is the formula to calculate the amount of S dopant precursor and the amount of titanium butoxide needed in grams?
Is there any particular formula to calculate it from mol% and weight%?
Dear friend Kuljit Kaur
Now, let's dive into the realm of dopants and precursors in style.
To calculate the amount of dopant needed, you can use the following formula:
Amount of Dopant (g)=[(Dopant Mol%/100)×Total moles of TiO2×Molar mass of S)
Let's break it down:
1. Calculate the total moles of TiO2 required:
Total moles of TiO2=Desired weight of TiO2 / Molar mass of TiO2
2. Calculate the amount of dopant precursor (thiourea) needed:
Amount of Thiourea (g)=Amount of Dopant (g)×(Molar mass of Thiourea / Molar mass of S)
3. Calculate the amount of titanium butoxide needed:
Amount of Titanium Butoxide (g)= (Total moles of TiO2×Molar mass of TiO2−Amount of Dopant (g))/ Molar mass of Titanium Butoxide
This formula takes into account the molar percentages of sulfur and the desired weight of TiO2.
Please note:
- Ensure consistency in units (either grams or moles).
- Be cautious with molar masses and conversions.
Feel free to plug in your values and calculate away! If you Kuljit Kaur have more questions or need clarifications, just throw them at me! 🚀
