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?

• chemistry -

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.
