You are watching: What is the mass of one mole of nitrogen gas
Actually fixed of 1 atom of nitrogen is 14 u(u=atomic massive unit) mass of 1 mole=mass the 1 atom of 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 actually 28 g mass. Together Nitrogen gas is consisted of of two Nitrogen facets Each nitrogen has actually Atmoic massive 14 g therefore N2 will have actually 2x14 = 28 g.
As we know that no. Of moles = given mass/molar mass likewise no. Mole = no.of particles(atoms,molecules etc)/avogadro no.(No) as we understand Avogadro"s number=6.023*10^23 therefore no. That moles=1/6.023*10^23 molar fixed of nitrogen = 14*2=28 for this reason no. Of moles = mass/28 1/6.023*10^23=mass/28 mass=28/6.023*10^23...
Nitrogen always exists as a dimer for this reason the massive of the molecular is to it is in calculated by multiplying atomic mass the nitrogen through 2 which way 14*2=28
Nitrogen molecule mass is 28 1mole of n2 is 28gram because that 1molecule of nitrogen divide 28by avagadro number 6.022 10^23 therefore ans will certainly be 28/6.022 10^23=4.64 10^-23
14 grams massive = number of moles x molar fixed 1 mole= loved one mass in grams that that certain element
mass that 1 mole=mass of 1 atom of 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
