The answer is 5,213.10 ex.23.
1.60 x 10^24 molecules
Molecules of NO2 contain covalent bonds

0.98 mol NO2 (6.022 X 10^23/1 mole NO2) = 5.90 X 10^23 atoms of nitrous oxide
Ga is Gallium and NO2 is the nitrite anion. Thus, Ga(NO2)3 is gallium nitrite.
4.651024 molecules of NO2 equals 7,721 moles.
1 mole NO2 = 46.0055g = 6.022 x 1023 molecules 19.6g NO2 x 6.022 x 1023 molecules/46.0055g = 2.57 x 1023 molecules NO2

1.60 x 10^24 molecules
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
ABigNumber.
The amount of 1 mole: 6.022 * 1023 (Avogadro's constant)
Molecules of NO2 contain covalent bonds
As every nitric oxide molecule has three atoms, this amount of molecules have 3.9 x 1022 atoms.
11.5 g NO2
N has 7 protons O has 8 protons (O2 therefore 16) So 1 molecule of NO2 gas has 7 + 16 = 23 protons 1 mole of NO2 gas (6.022 * 1023 molecules) have 138.506 * 1023 protons.
if you mean NO2, then 1 Nitrogen, 2 Oxygen. It is a toxic brown gas called nitrogen dioxide. if you mean No2, then no such substance exists. No is the element called nobelium. Since it is a metal it does not form molecules.
