Nitroglycerin (CaHsNgOp) is a powerful explosive. Its decomposition may be represented by 4C3H5NyOy 6N2 + 1 2co, + 101120 +02 This reaction generates a large amount of heat and gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. (a) What is the maximum amount of O2 in grams that can be obtained from 2.00x 10 g of nitroglycerin? (b) Calculate the percent yield in this reaction If the amount of Oz generated is found to be 6.53 g 9

Explanation / Answer

4 C3H5N3O9 ------------------ 6 N2 + 12CO2 +10 H2O + O2

mass of nitroglycerin = 2.00 x 10^2 grams= 200.00 grams

molar mass of nitroglycerin= 227.09 gram/mole

molar mass of O2 = 32 gram/mole

according to equation

4 moles of Nitroglycerin = 1 mole of O2

4 x 227.09 grams of Nitroglycerin = 32 grams of O2

200.00 grans of nitroglycerin = ?

                                                = 32 x 200.00/4x227.09 = 7.05 grams of O2

mass of O2 formed = 7.05 grams

Theoritical yiled of O2 = 7.05 grams

Actual yield of O2 =6.53 grams

Percent yield = Actual yield/theoritical yiles x100

%yiled = 6.53/7.05 x100 = 92.6%

Percent yield of O2= 92.6%.
