Suppose that you have 1.55grams of nitroglycerin( also known as nitroglycerine, trinitroglycerin, trinitroglycerine) in a 603.0 mili litres of steel container at 20 degree celsius and one atm pressure. An explosion occurs, increasing the temperature of the container and its contents to 425C degree celsius. The balanced equation is 4C3H5N3O9 -> 12CO2 + 10H2O + 6N2 + O2. determine How many mols of gas(air) were in the container originally?and How many moles of gas are in the container after the explosion? also explain what is the pressure (in atmospheres) inside the container after the explosion according to the ideal gas law?

The solution density = 1.013 g/mL and suppose that the density of pure water =1.00 g/mL. Determine the molality of this solution?
When you heat up popcorn, it loses water explosively and it pops. suppose a kernel of corn, weighing 0.125 grams weighs only 0.106 grams after popping.
While 1.22 g of a white solid, supposed of being pure cocaine, a molecular compound, is dissolved in 15.60 g of C6H6 the freezing point is lowered by 1.32 ¬0C. Compute the molar mass of the solid. Kf value for benzene = 5.12C/m.
Calculate the final temperature of the solution has a specific heat capacity =4.18 J/°C · g. assuming no heat lost
