Question

What is the initial molar concentration of oxygen in the beetle’s air bubble? I was told by someone else that the answer to this would be 0.294 mmol/L, but I’m pretty sure that this is wrong. Can you please provide further explanation?

Answer 1

To determine the initial molar concentration of oxygen in the beetle's air bubble, you can use the ideal gas law equation and the partial pressure of oxygen in the atmosphere.

Step-by-step explanation:

The initial molar concentration of oxygen in the beetle's air bubble can be determined by using the ideal gas law equation, which relates the pressure, volume, molar concentration, and temperature of a gas.

Assuming the bubble is at constant temperature and pressure, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

By rearranging the equation to solve for n (the number of moles), we have n = PV/RT. We know the volume and temperature, and from the given information, we can determine the pressure of oxygen using the partial pressure of oxygen in the atmosphere.
