Question: Under certain conditions, a zeolite with the ZSM-5 framework and formula NaAlSi 23 O 48 (A) can be synthesized. In the presence of (CH 3

Under certain conditions, a zeolite with the ZSM-5 framework and formula NaAlSi₂₃O₄₈ (A) can be synthesized. In the presence of (CH₃CH₂CH₂)₄NOH it is possible to prepare a material (B) with an extremely similar X-ray-diffraction pattern and the elemental composition N 0.86%, C 8.86%, H 1.73%, Al 1.66%, Si 39.70%, O 47.19% by weight. On heating to 500°C B loses 11.39% of its mass to form C.

(a) Calculate the empirical formula of B from the elemental analysis.

(b) Given the similarity in the X-ray-diffraction patterns of A and B, suggest a sensible chemical formula for B.

(c) Calculate the empirical formula of C.
