I have questions about incipient wetness impregnation

1) Can I get pore volume of support from BET test, then multiply pore volume (g/cm3) by the amount of support to get total pore volume ( total pore volume = total precursor solution volume)

2) I have a problem with calculations that related to this method, for example

Mass of activated carbon =10g as support

wt% of (NH4)6Mo7O24·4H2O= 15wt%

wt% of Ni(OCOCH3)2·4H2O = 3wt%

Total pore volume=3.5cm3

Demonstrate the calculation that done to know the required amount of NH4)6Mo7O24·4H2O and Ni(OCOCH3)2·4H2O (g) to prepare the precursor solution
