Write the equation and balance it.
Convert 1500g H2O2 to mols. mols = grams/molar mass
Convert mols H2O2 to mols H2O using the coefficients in the balanced equation.
Substitute mols H2O into PV = nRT and solve for volume at the conditions listed.
If the rocket engine contains 1500.0 grams of H2O2 and an excess of N2H4, what volume of water vapor will be produced when the rocket fires up to a temperature of 540°C and a pressure of 1.2atm?
