Gas Stoichiometry

Q. The decomposition of HMX (C4H8N8O8, MW = 296.16 g/mol), a powerful and relatively insensitive nitroamine explosive, occurs according to the reaction below: C4H8N8O8 (s) -> 3CO2(g) + C(s) + 2H2O (g) + 2H2 (g) + 4N2 (g) If 75.0 g of HMX decomposed in an evacuated container (no gas present) and the total pressure was measured to be 2.00 atm after the reaction, what is the partial pressure of each gas( in atm)?
