1. A sample of krypton gas at a pressure of 1.01 atm and a temperature of 29.8 °C, occupies a volume of 11.7 liters. If the gas is compressed at constant temperature to a volume of 6.67 liters, the pressure of the gas sample will be __ atm.

2. A sample of neon gas at a pressure of 0.963 atm and a temperature of 23.5 °C, occupies a volume of 621 mL. If the gas is allowed to expand at constant temperature until its pressure is 0.660 atm, the volume of the gas sample will be mL.

3. A sample of krypton gas at a pressure of 800 mm Hg and a temperature of 32 °C, occupies a volume of 14.8 liters. If the gas is cooled at constant pressure to a temperature of 6 °C, the volume of the gas sample will be L.

4. A sample of neon gas at a pressure of 0.782 atm and a temperature of 244 °C, occupies a volume of 558 mL. If the gas is heated at constant pressure until its volume is 727 mL, the temperature of the gas sample will be °C.
when 20ml mixture of O2 and O3 is burned.volume became 29ml and invisible in basis payregalol solution.what is the volume% of oxygen gass in real mixture?
a mixture of C2H2 and C3H8 is covered a certain volume at 80mmHg.mixture burn and make CO2 and H2O.if the pressure of CO2 is found 230mmHg at equal temperature and volume?
in the gasious mixture of C4H10,CH4 and CO , C4H10 is 40% of volume .when 200ml of mixture is burns with oxygen gass then what is the volume of CO2?
