A quantity of gas has a volume of 250.0 L at 17 C and 3.00 atm of pressure. To what volume must the gas be increased for the gas to be under STP conditions?
STP states that at STP the pressure is 1atm and the temperature is 273K.Therefore V2= (P1V1T2)/T1P2V2 = (3×250×273)/(290×1)V2 = 706 L

At s.t.p,a certain Mass of gas occupies a volume of 800cm3. Find the temperature at which the gas occupies 1000cm3 and has a pressure of 720mmhg
P1V1/T1 =P2v2/T21 × 800/273= 0.9504 × 1000/T22.9304 = 950.4/T22.9304 T2 = 950.4T2 = 324.324KT2 = 51.32°C

A sample of a gas occupies a volume of 1100 mL at 78ºC and 0.060 atm. What would be the new volume if the temperature decreased to 44ºC and the pressure increased to 1.31 atm?
p1 = 0,06 atm = 6079,5Pa V1 = 1100ml = 0,0011m3 T1 = 780C = 351 K p2 = 1,31 atm = 132735,8Pa T2 = 440C = 317 K V2...

At standard temperature and pressure (0 ∘C and 1.00 atm ), 1.00 mol of an ideal gas occupies a volume of 22.4 L. What volume would the same amount of gas occupy at the same pressure and 95 ∘C ?
P1 = P2 = 1.00 atm = constant;V1 = 22.4 L;T1 = 0 °C = 273.15 K;T2 = 95 °C = 368.15 K;V2 = unknown;Solution:(P1×V1)/(T1) = (P2×V2)/(T2);P1 = P2 =...

a certain quantity of gas occupies 10 liter at 25 degree Celsius and a pressure of 1 atm . at what pressure will the volume of gas be 1 liter
Due to ideal gas law:pV/T = constp1V1/T1 = p2V2/T2p2 = (p1*V1*T2)/(T1*V2) = 10 atm

The pressure in atm, if 8.25 X 10^-2 mole gas occupies a volume of 255 mL at 115ºC.
pV=nRT;p=nRT/V=8.25*10^(-2) * 8.314 * 388/0.255 =1043.65 Pa= 0.01 atmAnswer: 0.01 atm

At s.t.p., a certain mass of gas occupies a volume of 790 cm. Find the temperature at which the gas occupies 1000 cm and has a pressure of 726 mm Hg.
Let P1,V1 be the initial pressure,voloume and temparature of the gas at T1=273.15 and P2,V2 be the final pressure,voloume of tha gas T2 is the final temparature.Use the combined gas law:P1V1/T1...
