M C₉H₁₃NO₃=9x12+1x13+14+3x16=183g/mol

183g C₉H₁₃NO₃...............108gC..............13gH.............14gN..........48gO

100gC₉H₁₃NO₃....................x%C...............y%H.................z%N...........t%O

x=100x108/183=calculeaza

y=100x13/183=calculeaza

z=100x14/183=calculeaza

t=100x48/183=calculeaza
