A sample of C3H8 has 2.64 x 10^24 atoms. How many carbon atoms does the sample contain? What is the total mass of the sample? I dont even know where to start i mean it seems like a really simple question but the prof hasnt been through this topic. Im working a bit ahead just ...

Calculate the DELTA H(rxn), DELTA S(rxn), DELTA S(universe), DELTA G(rxn). For each system below indicate whether DELTA S and DELTA H are positive or negative. Then indicate if the reaction is entropy driven, enthalpy driven or neither. C3H8(g) + 2O2(g) => 3CO2(g) + 4H2O(g)
