What is the number of nitrogen molecules in 1.4 moles of n2?

How many atoms are in 1.4 g of nitrogen molecule N2? of atoms = 2 x 6.023 x 10^23 atoms. So, 1.4 g of Nitrogen contains [(2 x 6.023 x 10^23)/28]x1. 4 = 6.023 x 10^22 no. of atoms.

Can you calculate the number of moles present in 1.4 gram of nitrogen gas? We are given 1.4 g of dinitrogen gas. Dinitrogen gas has a chemical formula N2. Thus, the number of moles of dinitrogen gas in 1.4 g of dinitrogen gas are 0.05 mol. We know that one mole of any substance contains 6.022×1023 molecules of the substance.

How many molecules are present in 4g of nitrogen? The molar mass of nitrogen molecules is M(N2)=28g/mol. 4g nitrogen molecules are 0.143mol.
