1. A student performing this experiment records a volume of 175 mL at a barometric pressure of 755 torr and 93 ºC. Using the ideal Gas Law, calculate the number of moles of vapor in the flask
under these conditions. Let R = 0.0821 L-atm/mol-K and perform all necessary conversions
before calculating.

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

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.
