How much work is done by the system when 2.00 moles of O2 expand from a volume of 3.00 liters to a volume of 9 liters against a constant external pressure of 0.0100 atm?
Answer in units of J
W=P*change in vol chnge in vol = 9 - 3 = 6 litres = 0.006m3 W=0.006*0.01*101325=6.0795 joule Answer: 6.0795 joule

How much work is done by the system when
2.00 moles of O2 expand from a volume of
3.00 liters to a volume of 5.6 liters against a
constant external pressure of 0.0100 atm?
Answer in units of J
A = P x deltaV A = 1.013 x 10^3 x (5.6 - 3) x 2 mol А = 5.6728 x 10^3 J

How much work is done by the system when
2.00 moles of O2 expand from a volume of
3.00 liters to a volume of 6.9 liters against a
constant external pressure of 0.0100 atm?
Answer in units of J
The system is isobaric, so we can use the following equation for the work in system: A = pDelta;V p = 0.0100 atm - 1013.25 Pa; Delta;V = 0.0069 -...

How many liters of air will burn 30 liters of methane?
〖CH〗_4+〖2O〗_2→〖CO〗_2+〖2H〗_2 O ν=V/V_m ⇒ν~V V(O_2 )=2V(〖CH〗_4 )=30∙2=60 l. Air contains 21% O_2 by volume. V(air)=V(O_2 )/0.21=285.7≈286 l. Answer 286 l.

A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure>
What pressure would the gas exert if the volume was decreased to 2.00 liters?
According to the combined ideal gas equation:p1V1 = p2V2where p1 - initial pressure, V1 - initial volume, p2 - final pressure, V2 - final volume.From here:p2 = p1V1 / V2...

A sample of carbon dioxide occupies a volume of 3.50 liters at pressure 125 kPa. What pressure would the gas exert if its volume was decreased to 1.75 liters?
Boyle's Law can be expressed as P1V1 = P2V2initial pressure P1 = 125 Kpainitial volume V1 = 3.50 Lfinal pressure P2= ??final volume V2 = 1.75 LHence P2 = P1V1/V2P2 = 125 KPa...
