How many grams of nitroglycerin are needed to produce 25.0 grams of co2

Nitroglycerin  decomposes    according  to   the   following  equation

4 C3H5N309  --->  12 CO2 +  10 H20  +  6 N2 +O2
The  moles  of  CO2 =  25 /44(molar  mass  of  CO2)=  0.568  moles

the  mole  ratio  of  C3H5N3O9  to  CO2  IS  4:12   from  equation  above
therefore  the  moles  of  C3H5N3O9=( 0.568 x 4)/12= 0.189  moles
mass  of C3H5N3O9=moles  x  molar  mass  of  C3N5N3O9

That  is    0.189 mol x  227  g/mol=  42.903  grams

An ion is a charged particle that carries a net electrical charge. This charge can be either negative or positive Ions are formed when electrons are either taken or given away. There are different possible ways that this exchange of electrons can happen. Examples of this process are metals and non-metals. Metals lose electrons in order to become metals. Non-metals, on the other hand gain electrons to become non-metals.
