Given:
Vi = 6.00 L
Ti = 80.0 oC
= (80.0+273) K
= 353 K
Tf = 40.0 oC
= (40.0+273) K
= 313 K
use:
Vi/Ti = Vf/Tf
6.00 L / 353.0 K = Vf / 313.0 K
Vf = 5.32 L
Answer: 5.32 L

2. Boyle's Law. A given mass of air has a volume of 6.00 L at 101 atm. At constant temperature, the pressure decreased to 25.0 atm. Calculate the final volume for the gas. 20.01 24.21 24.21 6.00 L 1.50 L Page 2 of 20
What is the new volume, in liters, of a 25.0 L sample of air at 843.6 mmHg and 152°C that is compressed and cooled to 35°C and 1520 mmHg? 2.. A balloon containing 7.83 moles of He has a volume of 27.5 L at a certain temperature and pressure. What would be the volume of the balloon, in liters, if 1.00 mole of Heis removed from the balloon at constant temperature and pressure? 3. Calculate the pressure in atmospheres, of...
if
someone could do out 5 of these questions, that would be great.
thanks
Charles' Law Worksheet Name Directions: Calculate the following using Charles' Law. Assume constant pressure, number of moles, and containers are able to expand/contract. If a 6.50 L balloon at 22.0 °C is put into a refrigerator at 4.0 °C, calculate new volume. A 500 L balloon is heated from 20.0-75.0 C, calculate the final volume. A sample of gas is cooled from 180 °C to 25...
The air in a 6.00 L tank has a pressure of 1.30 atm . What is the final pressure, in atmospheres, when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas? A) 1.08 L B)2200 mL C)810 mL D)8.80 L
In the Charles' law portion of the experiment, Dick Xenon observed an air bubble volume of 0.38 mL at 75.1°C. Using Charles' law, what would you predict for the air bubble volume at 0.0°C?
1. A sample of an ideal gas has a volume of 2.26 L at 278 K and 1.10 atm. Calculate the pressure when the volume is 1.80 L and the temperature is 303 K. 2. The volume of a sample of hydrogen gas was decreased from 10.76 L to 4.05 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 8.39 atm, what pressure did the hydrogen gas exert before its volume was decreased? 3....
1.) Charles Law states: volume and temperature are directly proportional when pressure remains constant 2.) Boyle's Law states:_pressure and volume are inversely related when temperature remains constant 3.) What is the relative humidity of inspired gas in a person's airway if the water vapor content breathed in is 30 mg/L at normal body temperature? 30/44x100=68% 4.) Calculate the FEV1%. FVC is 6L and FEV1 is 4L 4/6=0.67 or 67% 5.) True or False: Vital Capacity is Total Lung Capacity -...
Combined Gas Relationship Since the Ideal Gas Law produces a constant (R), it can be used to look at a gas sample in which initial and final conditions have changed. The combined gas relationship is as follows P.V R=P.V2 n, T n2 T2 where P, Vi,and T, and n, are the initial pressure, volume, temperature, and number of moles of gas. The final conditions are represented by P, V2, T2 and n2. If any of the conditions in the initial...
i need help with the last four questions along with
step by step
he appropriate gas law to solve questions 1-6. Show work. (2 pts) A certain amount of a gas at a constant temperature has a pressure of 5.50 atm and a volume of 10.0 mL. If the volume is decreased to 125.0 mL, what is the resulting pressure of the gas? : 924 a4m 125 O P v (2 pts) If 0.722 L of a certain gas at...
An 80.0-L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.0atm. While the system is held at constant temperature, enough weight is placed on the piston to increase the external pressure to 10.0atm. For the resulting process, determine q(heat) and w(work) in units of kJ, and with proper signs. (Note: 1 L atm = 101.3 J)
