Answer:
47,9 kJ/g
Explanation:
The enthalpy of combustion is the change in energy due the reaction of combustion of n-octane. If the enthalpy is -4,79x10⁷ J/kg And knowing (1000J = 1kJ) (1000g = 1kg). The enthalpy of combustion expressed in kJ/g is:
= <em>47,9kJ/g</em>

Hey there! :
1) <span>
Solid Solutions </span>
Solid solutions are formed only by solutes and solid solvents. In
everyday life, the main examples of this type of solution are metallic alloys.
2) Liquid Solutions
Liquid solutions have liquid solvent, usually water, and solutes can be solid, liquid or gaseous.
3) Gaseous solutions
<span>This kind of solution is formed by the only mixture of gases. Air is an
example, as its approximate composition is 78% nitrogen gas, 21% oxygen gas and
1% of other gases.</span>
