The heat released from the combustion of 0.05 g of white phosphorus increases the temperature if 150g of water from 25 C to 31.5 C. Calculate the enthalpy change for the reaction.

dH = mass H2O x specific heat H2O x (Tfinal-Tinitial)
This will give you the enthalpy change for the reaction as stated in the problem and that is for 0.05g P. Generally these problems don't want that; they want the enthalpy change per mol but this problem doesn't ask for that.
