In the following reaction, how many grams of nitroglycerin C3H5(NO3)3 will decompose to give 25 grams of CO2?
gogolik [260]

4C₃H₅(NO₃)₃_{(l)} ------> 12CO₂_{(g)} + 6N₂_{(g)} +  10H₂O_{(g)}  +  O₂_{(g)}

mol of CO₂  =  \frac{mass}{molar mass}

                    =  \frac{25g}{44.01 g/mol}

mol ratio of  CO₂ :  C₃H₅(NO₃)₃

                    12    :     4

∴  if  mole of CO₂  =  0.568 mol

then   "       "   C₃H₅(NO₃)₃  =  \frac{0.568 mol}{12}  *  4

                                           = 0.189 mol


∴ mass of nitroglycerin  =  mole  *  Mr

                                       =  0.189 mol  *  227.0995 g / mol

                                       =  43.00 g
