For calculation you can use this formula
n[mol]=m[g]/M[mol/g]
The molar mass of nitrogen molecules is M(N2)=28g/mol.
n = 4g / 28g/mol= 0.143mol
4g nitrogen molecules are 0.143mol.
n[mol]=m[g]/M[mol/g]
The molar mass of nitrogen molecules is M(N2)=28g/mol.
n = 4g / 28g/mol= 0.143mol
4g nitrogen molecules are 0.143mol.
