a) The ideal gas pressure can be calculated using the ideal gas law: P = nRT/V P = 10x8.314x273/0.01 = 2269848 Pa b) The real gas pressure can be calculated using the Van der Waals law: (p+n2a/V2) (V - nb) = nRT

What is the pressure of a 50.0L tank that contains 4.04kg of oxygen, O2, at 23’c? assume that the ideal gas law is obeyed and use R=0.0821 L atm/mol K

PV = nRTn = mass/molar Massn = 4.04×10^3/32 g/mol= 126.25 molP = nRT/V= (126.25 mole) × (0.0821Latm/mol /K)(93+273)K)/50 LP = 61.36154 atm

If a piece of metal with a temperature of 90.0oC is added to a container of water at 24.0oC, the energy will

The colder water will warm up (heat energy "flows" in to it). The warmer metal will cool down (heat energy "flows" out of it). The whole mixture will wind up...

A mixture of 6.5 mole of H2 at 3.5 moles of O2 gas was contained in a 3m³ container at 273k.calculate the pressure of the gas mixture

6.5 × 3.5 × 273/10 × 3 × 273= 22.75/10= 2.275atm

A flask contain 1.00 mol of He(g) at 273K and 1 atm. How many molecules in the sample have speeds in the range of 90.000 to 90.002 m/s ?

Using ideal gas law equation,PV=nRTV=224ml=0.224L, P=1atm, R=0.082 and T=273K1atm×0.224L=n×0.082Latm mol−1K−1×273Kn=0.01 mol0.01 mol of gas contains 1g.1mol of gas =100gTherefore, 6.022×1023×3 atoms=100 gMass of one atom =5.53×10−23gRead more on Brainly.in -...

A sample of gas at 25.0oC has a volume of 3.20L at a pressure of 100kPa. What would its volume be if the pressure was increased to 1.3atm and the temperature was decreased to -57.0oC?

T1=25.0 C= 298 KV1=3.2 Lp1=100 kPaT2=-57.0 C = 216 Kp2=1.3 atm= 101.3 * 1.3 (kPa)=131.7 kPaV2 - ?(p1V1)/T1=(p2V2)/T2;V2=(p1V1*T2)/(T1*p2);V2=(100*3.2*216)/(298*131.7)=1.76 LAnswer : 1.76 (L)
