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).

To find the atomic mass, multiply the individual atomic masses with their relative abundances and add them up.
10.012*0.1991 + 11.009*0.8009 = 10.810 amu (5 s.f.)
Element X is Boron.
