Dear friend Inam Ullah

To calculate the required weight of each reagent for the synthesis of a zeolite with a particular molar composition, you can use the following steps:

1. Write out the balanced chemical equation for the synthesis reaction.

2. Determine the number of moles of each reactant needed to produce the desired molar composition of the zeolite.

3. Convert the number of moles to mass using the molecular weight of each reactant.

Here is an example calculation for the synthesis of NaA zeolite with the given molar composition:

1. The balanced chemical equation for the synthesis of NaA zeolite is:

1.8 Al(O-iPr)3 + 11.25 Si(OH)4 + 0.6 NaOH + 2 (TMAOH) + 700 H2O → NaA zeolite + 6 (iPrOH) + 11.25 H2SiO3(OH)

2. To produce 1 mole of NaA zeolite with the given molar composition, we need:

- 1.8 moles of Al(O-iPr)3

- 11.25 moles of Si(OH)4

- 0.6 moles of NaOH

- 2 moles of TMAOH.5H2O

- 700 moles of H2O

3. To convert the moles to mass, we need to multiply the number of moles by the molecular weight of each reactant. The molecular weights are:

- Al(O-iPr)3: 294.29 g/mol

- Si(OH)4: 96.11 g/mol

- NaOH: 40.00 g/mol

- TMAOH.5H2O: 121.19 g/mol

- H2O: 18.02 g/mol

Therefore, the required weights of each reactant are:

- Al(O-iPr)3: 1.8 moles x 294.29 g/mol = 529.72 g

- Si(OH)4: 11.25 moles x 96.11 g/mol = 1081.74 g

- NaOH: 0.6 moles x 40.00 g/mol = 24.00 g

- TMAOH.5H2O: 2 moles x 121.19 g/mol = 242.38 g

- H2O: 700 moles x 18.02 g/mol = 12614.00 g

Therefore, to synthesize NaA zeolite with the given molar composition, you would need 529.72 g of Al(O-iPr)3, 1081.74 g of Si(OH)4, 24.00 g of NaOH, 242.38 g of TMAOH.5H2O, and 12614.00 g of water.
