If 395mL of O2(g) is collected over water at 25 degrees Celsius and 749.2 mmHg barometric pressure, then what is the percent by mass of Ag2O in the sample? The vapor pressure of water atР”Р„ sample of argon gas has a volume of 735 mL at a pressure of 1.20 atm and a temp of 112 degrees Celsius. 975 atm V= 2.50 L n=Р”Р„ 8.07g sample of impure Ag2O decomposes into solid silver and O2(g). What was the temperature of the propane in the flask. After the sample was collected, the gas pressure was found to be 741 mmHg. what mass of nitrogen is present in the sample?Р”Р„ 2.50 L flask was used to collect a 5.65 g sample of propane gas, C3H8. The total pressure of the sample is 725mmHg and the partial pressure of argon is 231 mmHg. the table below shows the initial temperature, pressure, and volume of theР”Р„ 255mL gas sample contains argon and nitrogen at a temperature of 65 degrees celsius. the volume of the gas sample is changed when both the temperature and the pressure of the sample are increased. Not sure of formula for thisР”Р„ sample of helium gas is in a closed system with a movable piston. What is the pressure of the nitrogen gas if the atmospheric pressure is 744 mmHg? Answer in units of mmHg.

if the pressure is changed to 0.155 atm calculate the new volumeР”Р„ sample of nitrogen gas is collected overwater at a temperature of 23РІвЂ”В¦C. A sample of gas has the pressure of 1120 mmhg and volume of 2.00 L.

633 mmhg to atm
