Pls answer all the 7 questions. I really need help and I have to give this in by 3pm
GAS LAW CALCULATIONS: Problem Set B. (SHOW ALL WORK) 1) A sealed flask contains 2.00 moles of helium and 3.00 moles of nitrogen. If the total pressure of the container is 200. KPa, what is the partial pressure of the nitrogen? 2) A 6.55 Liter gas canister has a pressure gauge that reads 4.45 atmospheres and a temperature gauge that reads 31.5 °C. How many moles of gas are in the container? 29 3) At a temperature of 290. Kelvin, a 500. milliliter gas sample has pressure of 1.50 atmospheres. If the pressure is changed to 3.75 atmospheres at what temperature will the gas sample have a volume of 675 milliliters? 4) A gas occupies a volume of 30.0 milliliters at STP. If the temperature is increased to 350. Kelvin, what will the new volume be if pressure remains constant? 5) Whose law is demonstrated by #4? 6) How much heat energy is needed to convert 350. grams of water to water vapor? 7) 640. joules of energy are released when 4 grams of water is cooled. If the initial temperature of the water was 99.0°C, what would the final temperature be? 8) How much heat is transferred if 550. grams of liquid water is frozen/31 9) Is the situation in #8 exothermic or endothermic? (Explain your answer) 30
