page:01 Answer:- According to the given problem, to calculate the censity of Magnesium oxick (nego). Given, Ốc - 21H12 916 - 0:0660m Sia - 902 NQ: 0.132nm. * calculate ozato beleween the cation and anion :- the coordination number 2 acl ra - 0.066 nm 0.132 nm 910 ... station of. $10 =0.5 the coordination number is 6. the magnesium oxide cogol has same gatic as well as coordination numben. as that of Mact.page:02 Hence, the given ngi has the same crystal structure of Naci. thena --the atomic mass of rigt2 - AQ = 24:312 g/mol the atomic mass of 0-2 = AC a 16 glmol. * Calculate the density of Magnesium oxide (Mgo) :- het, Densite nx(ACHAR) - O VCXNO. Here, AC: 16g/mol AX 24-312 g mol vca volume of unit cell 2 sx ora tax rc 22x0.132 + 2X0.066 a 0.264+ 0.132 Vc = 0.396 Na z magando number - Na : 620 23 X 1095pageros n2 8x1/2 + 8 X1 / =1+3 กอนุ Substitute tee values in equation. Density < 4x (16 g/mol + 24:312 g/mol) 0.396 X 6.093 x 1083 eux (.312) g/mol 2.385x1013 - 6.76x1 = 646 X1622X108 0.616 g1 cm . Lensity of Magnesium oxide (mgo) : 0.64691cm?
