Concept explainers
(a)
Interpretation:
The number of molecules of nitrogen should be determined.
Concept Introduction:
When two non-reactive gases mix, the pressure, volume and temperature could be change. The new pressure, volume and temperature can be calculated with the help of ideal gas equation.
The ideal gas equation is given by:
PV = nRT.
(b)
Interpretation:
To calculate the total number of moles of both nitrogen and helium gas after gases are mixed.
Concept Introduction:
When two non-reactive gases mix, the pressure, volume and temperature could be change. The new pressure, volume and temperature can be calculated with the help of ideal gas equation.
(c)
Interpretation:
The beginning pressure of cylinder B having Only helium gas should be calculated.
Concept Introduction:
When two non-reactive gases mix, the pressure, volume and temperature could be change. The new pressure, volume and temperature can be calculated with the help of ideal gas equation.
(d)
Interpretation:
The graph for the relationship between pressure and volume for the helium gas showing helium gas before and after the cylinders were connect should be drawn and also explain the answer by addressing variables P, V, n and T.
