Answer to Question #58008 in General Chemistry for Brook

Question

A gas at 1.00 atm occupies 5.00 L. Under what pressure will the volume be 10.0 L if the temperature remains constant?

Answer 1

The ideal gas law is written as:
PV = nRT
where n - number of moles of gas;
P - gas pressure (e.g., atm)
V - gas volume (liters);
T - gas temperature (in Kelvin);
R - gas constant (0.0821(L*atm)/(mol*K) )
n and T are constant, R is always constant
PV = constant
P1V1 = P2V2
1*5 = P2*10
P2 = 0.5 atm
Answer: Under the 0.5 atm pressure the volume will be 10.0 L
