Thank you Prof. Ali Nematollahzadeh for your contribution, i applied the equation and i think it worked, though am yet to review this wheeling equation. Thank you once again.

Thank you Dr. Hai Tran, your equation (12) confirm that given by Prof. Ali Nematollahzadeh above.

Interesting question.

Please, do you known whats means the unity cc/g ?

@Ricardo, cc/g is grams per cubic centimeter

Dear Moses.

Thank you so much for information.

Just note that cc/g differs from g/cc. One is density the other specific volume. the question is cc/g, so that will be cubic centimeter per gram which refers to specific volume,i.e; volume occupied by unit mass. Ricardo Resende Moses Kolade David

Pore volume (cm3/g)

That's right: volume/mass (cm3/g) the inverse of density

I do agree with Mrs Yusuf about cc/g and g/cc
