Retailers purchase gasoline by weight so they get a constant
amount of
gasoline per dollar (as long as the price is constant). We buy
gasoline by
volume. The enthalpy of combustion of 1.00 L of gasoline is –3.539
x 10 4 kJ
at 15.6 o C when gasoline has a density of 0.73722 g/mL. What would
the
enthalpy of combustion of 1.00 L of gasoline be at 32.2 o C when
gasoline
has a density of 0.72210 g/mL?

Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking
Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking. You need to boil 15.5 L of water using your natrual gas (primarily methane) stove. What volume of natural gas is needed to boil the water if only 15.6% of the heat generated goes towards heating the water. Assume the density of methane is 0.660g/L, the density of water is 1.00 g/ml., and that...

Octane, a component of gasoline, can undergo the following combustion with an excess of oxygen gas: 2 C8H18 (ℓ) + 25 O2 (g) → 16 CO2 (g) + 18 H2O (ℓ) 10.0 mL of octane and 1.50 atm of oxygen gas are placed in a 20.0 L container at 20.0°C. Calculate the total pressure in the container after complete combustion (in atm). (Assume the vapor pressures of water and octane are negligible and temperature and volume remain constant. The density...
