The number is already rounded to a greater extent than that!
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g

Avogadro's Number = Avogadro's number = 6.0221415 × 10236.02×1023 (abbreviated); this is the number of atoms, ions, molecules, or anything else in 1 mole. 0.33 moles of water would have 0.33·6.02×1023 = 1.99×1023 molecules. However water's formula is H2O, so it has 3 atoms per molecule. (0.33 moles) × (6.02×1023 molecules per mole) = 1.99×1023 molecules.1.99×1023 molecules × 3 atoms per molecule = 5.96×1023 atoms(0.33 moles) × (6.0221415 × 1023molecules per mole) = 1.987306695×1023 molecules.1.987306695×1023 molecules × 3 atoms per molecule =5.961920085 1023 atomsI would use the rounded answer, 5.96×1023 atoms
Ok let me see the answer ok am confused again
93% of 1,023= 93% * 1023= 0.93 * 1023= 951.39
