please answer these questions. thank you

1. Porous gold shown below is synthesized with a cubic-close-packed nanosphere template with sphere diameter of 800nm. The density of bulk Au is 19.3g/cm3. Estimate (1) the porosity (2) specific pore volume (cm3/g)(3) specific surface area (m2/g) and (4) the apparent densitv. 2. Based on the CTAB phase diagram below, design a process to synthesize MCM41 CTAB as surfactant. Describe the steps of the synthesis, the chemistry involved, and specify the precursor, pH range, surfactant concentrations, and the reaction temperature. Note that the autoclave has a temperature limit of 200C
