Question

59. 60. 61. (d) If the temperature of Flask X is lowered and that of Flask Z is raised, which of the three flasks will contain the largest number of moles of gas? A 14.4 g sample of an unknown gas has a volume of 8.00 L at 760 mmHg and 25 °C. What is the molar mass of the gas? If a basketball is inflated to an internal pressure of 1.32 atm at 25 °C and then taken outside, where the temperature is 10 °C, what will be the final pressure in the ball? Consider a room that is 4.61 m x 9.48 m X 2.63 m. What mass in kg of CO2(g) at STP will the room hold? A gas at 750 mmHg and 27 °C has a density of 2.32 g/L. Which of the following could it be: CO, Kr, H S, or C4H10? The density (mass per unit volume) of air in the atmosphere is proportional to the atmospheric pressure. At sea level, mean atmospheric pressure is 760 mmHg. Boyle's law, which relates the pressure of a given amount of gas to its volume, indicates that density decreases with altitude in the atmoenhora A ltitude increase there ie lece mace of air 62.

Answer 1

60answer 1.25atm

6 from the data Internal outside pressure (P) = 1.32 atm pressure (P2) - ? Temperature ( *y) = 25°C Temperature (T2) = loc = 25+273 = (0+273) T = 298K T2 = 283k In the ball Volume is constant. From Charle's - Gay-Lussac's law, The pressure of a given mass of a gas is directly proportional to the absolute temperature at constant Volume . Para P L = P. substitute all the value 298 K 2836 3 l (1 32 atm) (283H) 2986 - = las atm A Final pressure in the ball (P₂) = 1.25 atm
