What is its volume at the final temperature? A bag of potato chips contains 585 mL of air at 25 degree C and a pressure of 765 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 442 mm Hg and the temperature is 5.0 degree C? Calculate the mass of 125 mL SF_6 gas sample at STP. How many liters of NH_3 form when 24.8 L of H_2(g) (measured at STP) reacts with 18.1 L N_2 to form NH_3 according to this reaction: N_2(g) + 3 H_2(g) rightarrow 2 NH_3(g)? What is the density of a sample of sulfur trioxide gas at 2.3 atm and 75 degree C? Consider the reaction for the synthesis of nitric acid: 3 NO_2(g) + H_2O(I) rightarrow 2 HNO_3(aq) + NO(g). If 12.8 L ofNO_2 (g), measured at STP, is allowed to react with 14.9 g of water (18.01528 g/mole), What is the theoretical yield of HNO_3 in grams? The volume of HNO_3 that forms is found to be 470 mL at 0.500 M. What is the percent yield of the reaction?

Explanation / Answer

1)
Vi = 48.3 mL
Ti = 22 oC = (22 + 273) K = 295 K
Tf = 87 oC = (87 + 273) K =360 K

use:
Vf/Vi = Tf/Ti
Vf/48.3 = 360/295
Vf = 58.9 mL

Answer: 58.9 mL
