A certain chemical reaction releases 233.kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes 2.13J of heat energy to raise the temperature of this calorimeter by 1°C

Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 11.3°C

How would you calculate the number of moles of reactant that were consumed?
