1) An ideal gas initially at 1.2 atm and 27 degrees celcius is heated in a constant volume, sealed container to 75 degrees celcius. What is the finl pressure? 2) If a 15.2 Liter sample of ethane gas is at 26 degrees celcius and 1.04atm, what is the number of moles of gas in the sample? 3) What is the concentration in Molarity if 36.0 grams of MgCl2 is dissolved in water to make a totale volume of 250mL. 4)...
The density of a gas under NORMAL conditions (STP, 273K and 1atm) is 2.4 grams/Liter. There is an ideal gas inside a 20L volume container at a temp of 5 degrees celcius. The gas is allowed to leave the container, causing the pressure inside to decrease by 0.85 atm. (the temperature inside remains constant). What is the mass of the gas that is released?
A 1.16 mol sample of Xe gas is confined in a 27.6 liter container at 17.1 °C If the amount of gas is increased to 1.74 mol, holding the volume and temperature constant, the pressure will increase because: Choose all that apply. 一with more molecules per unit volume, the molecules hit the walls of the container more often. O With higher average speeds, on average the molecules hit the walls of the container with more force. With more molecules in...
A 5.30 liter container holds 0.250 moles of nitrogen at a temperature of 211 degrees Celsius. What is the pressure of the gas in kilopascals.
A 1.72 mol sample of Kr gas is confined in a 40.4 liter container at 13.2 °C. If the amount of gas is decreased to 0.860 mol, holding the volume and temperature constant, the pressure will decrease because: Choose all that apply. As the number of molecule-wall collisions increases, the force per collision decreases. With fewer molecules per unit volume, the molecules hit the walls of the container less often. With lower average speeds, on average the molecules hit the...
Part A) A 1.37 mol sample of Xe gas is confined in a 32.7 liter container at 18.1 °C. If the temperature of the gas sample is raised to 41.5 °C holding the volume constant, the average kinetic energy will remain the same decrease not enough information to answer the question increase Part B) A 1.24 mol sample of O2 gas is confined in a 29.2 liter container at 13.5 °C. If the temperature of the gas sample is lowered...
8.23*10^-3 mol of hydrogen gas occupies 480ml container at 48 degrees celcius. what is the pressure in torr?
A closed container in lab contains a sample of oxygen gas. When the temperature in lab is 18.8 degrees Celcius, the pressure in the container is 3.10 atm. What would the pressure be if the temperature dropped to 29.2 degrees Celcius? atm Enter an interer or decimal number with exactly 3 significant figures more If 14.0 mol of If 14.0 mols of Ne gas occupies 75.80 L, how many mol of Ne would occupy 692.1 under the same temperature and...
An ideal gas is at a temperature of 30 degrees celcius and a pressure of 2.00 atmospheres. What is the number of particles per unit volume of the gas? (Answer should be 4.86x10^25/m^3) PLEASE SHOW WORK
If the pressure of a gas in a container is increased while the number of molecules and temperature are held constant. What must happen? Volume must increase. k must decrease k must increase Volume must decrease.
