The standard enthalpy of formation of propene c3h6 is 20.6 kj per mole What is the heat of combustion of one mole of c3h6 the heats of formation of co2g and h2ol are -394 kjmole and -285.8?
Just set up the balanced equation to solve this. C3H6 (s) + (9/2)O2(g) ---> 3CO2(g) + 3H2O (l). Now it is only a matter of adding and subtracting the appropriate formation values.

What is the molarity of a solution containing 23G of nacl in 500 ml solution?
molarity of a solution means mols per liter.First, you need to convert 23 grams on NaCl into mols. 23g divided by molar mass (58.44g/mol) which gives you .394 mols.Now, you need to convert 500ml to L which moves the decimal three places to the left, giving you .500L of solution.Finally, divide the mols over solution to get .787M
