The enthalpy of combustion of glucose (molecular weight = 180 g mol$^{-1}$) is $-2840$ kJ mol$^{-1}$. Then the amount of heat evolved when $0.9$ g of glucose is burnt, will be}
Show Hint
Always convert mass into moles before using enthalpy values given per mole. Also, negative enthalpy indicates heat is evolved.
