Question

now assume that the gas is not behaving ideally (so you must use the van der waals equation). for this gas sample, a is 2.1 atm l2 mol-2 and b is 0.042 l mol-1. what is the pressure of the gas sample? report your answer in atmospheres to the nearest whole number.

Answer 1

The pressure of the gas sample cannot be determined without additional information like the volume, temperature, and moles of gas.

Step-by-step explanation:

The pressure of the gas sample using the van der Waals equation cannot be determined from the information provided because the question lacks specific values for the volume, temperature, and amount (moles) of the gas. The van der Waals equation is P = \left(\frac{nRT}{V-nb}\right) - \frac{an^2}{V^2}, where a and b are the van der Waals constants. For a given sample, you would need to know the number of moles (n), temperature (T), and volume (V) of the gas to be able to calculate the pressure (P). Since these values are not provided, the pressure cannot be calculated.
