The answer to question 8 is
Ethanol's Molar Heat of Combustion. ... Heats of combustion are quoted as positive numbers while the enthalpy changes of combustion reactions (ΔH) are quoted as negative numbers, as combustion reactions are always exothermic. Heats of combustion are typically stated in kilojoules per mole (kJ/mol. or kJ mol. -1).

The answer is "<span>the quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure"</span>
Answer:
4 g/ml
Explanation:
Density is defined as the amount of a substance (mass) in a certain volume. So the equation is D = m/v.
For this example, D = 60 g/15 ml. so the answer would be 4 g/ml.
