Hey there Abdullah Alayoub! Absolutely, you Abdullah Alayoub can calculate the bulk density using the information you Abdullah Alayoub have. It's a bit of a complex process, but let's break it down. Bulk density is typically defined as mass per unit volume, so you'd need to use the crystal size, specific surface area, average pore size, and total pore volume to derive the volume of the material.

Here's a simplified formula for bulk density (ρ_bulk):

ρbulk​=m​/V, Where: m is the mass of your Ni−Fe/TiO2 sample and V is the total volume of the sample

Now, using the physical properties you have:

V = V_{crystal} + V_{pores}

V_{crystal} = m_{crystal}/{{density}_{crystal}}

V_{pores} = V_{total}/{specific surface area}

V_{total} = {total pore volume} + {crystal volume}

{crystal volume} = {m_{crystal}/{density}{crystal}}

{total pore volume} = {average pore size} X {specific surface area}

Once you have V, plug it back into the bulk density formula. It's a bit of a process, but it should get you Abdullah Alayoub there. If you Abdullah Alayoub need further assistance, feel free to ask!

Dr, Emil Obeid, What do you think? These are the information that I have below

Уважаемый Абдулла Алайуб! Ваш не прямой метод даст приблизительное значение истинной плотности. Погрешности сведут к нулю ценность данных. Нужна пикнометрия.
