Ammonia (nh3) boils at -33∘c; at this temperature it has a density of 0.81 g/cm3. the enthalpy of formation of nh3(g) is -46.2 kj/mol, and the enthalpy of vaporization of nh3(l) is 23.2 kj/mol calculate the enthalpy change when 5 l of liquid nh3 is burned in air to give n2(g) and h2o(g).

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
