You are watching: Mass of nitrogen atom in kg
Actually massive of 1 atom the nitrogen is 14 u(u=atomic mass unit) massive of 1 mole=mass of 1 atom that nitrogen * Avagadro"s no. * 1.6 *10^ (-24)(since 1 amu=1.6* 10^(-24) gm) =14*6.022*10^(23)*1.6* 10^(-24) =14 gm
1 mole that Nitrogen has actually 28 g mass. As Nitrogen gas is consisted of of 2 Nitrogen aspects Each nitrogen has Atmoic massive 14 g so N2 will have actually 2x14 = 28 g.
As we know that no. Of moles = offered mass/molar mass additionally no. Moles = no.of particles(atoms,molecules etc)/avogadro no.(No) together we know Avogadro"s number=6.023*10^23 for this reason no. Of moles=1/6.023*10^23 molar massive of nitrogen = 14*2=28 so no. Of mole = mass/28 1/6.023*10^23=mass/28 mass=28/6.023*10^23...
Nitrogen always exists as a dimer therefore the fixed of the molecule is to it is in calculated by multiplying atomic mass that nitrogen by 2 which way 14*2=28
Nitrogen molecule mass is 28 1mole that n2 is 28gram because that 1molecule the nitrogen divide 28by avagadro number 6.022 10^23 for this reason ans will be 28/6.022 10^23=4.64 10^-23
14 grams fixed = number of moles x molar mass 1 mole= relative mass in grams of that specific element
mass of 1 mole=mass that 1 atom that nitrogen * Avagadro"s no. * 1.6 *10^ (-24)(since 1 amu=1.6* 10^(-24) gm) =14*6.022*10^(23)*1.6* 10^(-24) =14 gm
