Maximum number of molecules of dinitrogen in a container of 2 litre will be present if the container has the highest mass of dinitrogen. This is because the number of molecules of dinitrogen is directly proportional to its mass.
(a) 2.5 gram molecules of dinitrogen: This is an incorrect unit as molecules do not have a mass. The correct unit should be grams of dinitrogen.
(b) 4 gram atom of Nitrogen: 1 mole of nitrogen contains Avogadro's number (6.02 x 10^23) atoms. Therefore, 4 gram atoms of nitrogen will contain (4/14) moles of nitrogen atoms. This is equivalent to (4/14) x 6.02 x 10^23 = 1.72 x 10^23 nitrogen atoms. Since each molecule of dinitrogen contains 2 nitrogen atoms, the number of molecules of dinitrogen will be 1.72 x 10^23 / 2 = 8.6 x 10^22 molecules.
(c) 3.01×10^24N atoms: This is equivalent to (3.01 x 10^24) / (6.02 x 10^23) = 5 moles of nitrogen atoms. Since each molecule of dinitrogen contains 2 nitrogen atoms, the number of molecules of dinitrogen will be 5 x (6.02 x 10^23) / 2 = 1.51 x 10^24 molecules.
(d) 84 gram of dinitrogen: The molar mass of dinitrogen is 28 g/mol. Therefore, 84 g of dinitrogen is equivalent to 3 moles of dinitrogen. Since each mole of dinitrogen contains Avogadro's number (6.02 x 10^23) molecules, the total number of molecules of dinitrogen will be 3 x (6.02 x 10^23) = 1.81 x 10^24 molecules.
Therefore, option (d) 84 gram of dinitrogen contains the maximum number of molecules of dinitrogen in a container of 2 litre.

Yes d is answer..Bcz 84÷14 =6 so 6 moles of dinitrigen is present..So..6×6.023×10^23 molecules are present
