An organic compound P containing carbon, hydrogen and oxygen only was burnt in excess oxygen. 0.36g of the compound was combusted producing 0.88g of carbon dioxide and 0.36g of water. If the molar mass of compound P is 72, what is the empirical and molecular formula of P?

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.

i think its 100

i hope this !
