You are watching: What is the mass of one mole of nitrogen gas
Actually massive of 1 atom of nitrogen is 14 u(u=atomic fixed unit) fixed 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
1 mole of Nitrogen has 28 g mass. Together Nitrogen gas is made up of two Nitrogen aspects Each nitrogen has Atmoic fixed 14 g so N2 will have actually 2x14 = 28 g.
As we know that no. Of moles = provided mass/molar mass likewise no. Moles = no.of particles(atoms,molecules etc)/avogadro no.(No) as we understand Avogadro"s number=6.023*10^23 so no. Of moles=1/6.023*10^23 molar mass 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 together a dimer therefore the mass of the molecule is to be calculated by multiplying atom mass that nitrogen through 2 which method 14*2=28
Nitrogen molecule mass is 28 1mole of n2 is 28gram for 1molecule of nitrogen division 28by avagadro number 6.022 10^23 therefore ans will certainly be 28/6.022 10^23=4.64 10^-23
14 grams fixed = variety of moles x molar fixed 1 mole= relative mass in grams that that details element
mass the 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
