Let's see. There are 3 oxygens in that nitrate group (NO3), and there are 3 nitrate groups (NO3)3. 3 x 3 is 9. The answer is nine oxygen atoms in this molecule.

There are 9 oxygen atoms. The oxygen is represented by O. The NO3 of (NO3)3 part shows that 3 oxygens are bonded to a N atom. The 3 outside the parentheses shows that there are 3 separate NO3 groups. So: 3 times 3 is 9

just count the O and apply multiplicity rule for brackets.

O3*3=9 Oxygen atoms.

9

(NO3)3 means you have 3 NO3's so 9 oxygens/molecule

Silver Sulfate, Ag2SO4. a million mole is Avagadro's style (6.022 x 10^23) molecules. with the help of definition .698 mole is .698 x 6.022 x 10^23 = 4.20 x 10^23 with the help of math There are 4 atoms of O in step with molecule of Ag2SO4. with the help of formula consequently, there are (4.20 x 10^23) x 4 atoms = a million.sixty 8 x 10^24 atoms. with the help of math
