ATOMIC MASSES OF

#N->14" g/mol"#

#O->16" g/mol"#

Molar mass of #N_2O_3=2xx14+3xx16=76" g/mol"#

We know 1mol of any element or compound contains #6.023xx10^23#molecules.

So #4.3xx10^21# molecules of #N_2O_3# will be

#(4.3xx10^21)/(6.023xx10^23)mole

#=4.3/6.023xx10^-2mol#

#=4.3/6.023xx10^-2molxx76g/"mol"#

#=0.5426g#
