For 1 mol of gas, the plot of pV vs. p is shown below. p is the pressure and V is the volume of the gas. What is the value of compressibility factor at point A?
When solving compressibility factor problems:
Start by expressing and substitute the appropriate gas law (e.g., Van der Waals equation).
Expand and simplify using the given conditions to isolate terms involving , , and .
Pay attention to the behavior of in real gas scenarios.
For 1 mole of real gas, From the graph, for a real gas is less than for an ideal gas at point A. Thus, . The compressibility factor is given by: Substituting into the definition of and simplifying:
0.1 mole of compound S will weigh ...... g, (given the molar mass in g mol C = 12, H = 1, O = 16)
The molar mass of the water insoluble product formed from the fusion of chromite ore with in presence of is ....... g mol:
Let be the solution of the differential equation
such that , then is equal to:
Find the IUPAC name of the compound.
If , then is: 32
