Assume that you have 1.65g of nitroglycerin in a 614.0 mL steel container at 20.0 C and 1.00 atm pressure. An explosion occurs, raising the temperature of the container and its contents to 425 C .The balanced equation is 4C3H5N3O9=12CO2+10H2O+6N2+O2 a)How many moles of nitroglycerin were in the container originally? b)How many moles of gas (air) were in the container originally? c)How many moles of gas are in the container after the explosion? d)What is the pressure (in atmospheres) inside the container after the explosion according to the ideal gas law
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
