hello forum I am working on NKBT Perovskite material.My formula is (Na0.5 K0.5)0.5 (Bi)0.5 TiO3 I am using NaNo3,KNO3,Bi(NO3)3.5H2O,TiO2 powders my question is how much powder in grams I have to take according to stichometry. Do I have to work in wt% or in Mole %. is there any difference? I am using this method NaNO3 in Grms = molecular wt of NaNO3*no.of moles of NaNO3*5(i want to make 5 grms of total sample)/total molecular weight of compound. Is this correct? plz reply. actuall I am a physics major.
