Calculate the number of moles of h2o2 required to produce 0.08 moles of hno3 by the following reaction. 7 h2o2 + n2h4 2 hno3 + 8 h2o
im having trouble with stoichiometry

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

is there any options? maybe im just not seeing them but i need the options to
