What pressure is required to achieve a CO2 concentration of 4.8010-2 at 20C?

Answer 1

To determine the pressure required to achieve a CO2 concentration of (4.80 \times 10^{-2}) at 20°C, we can use the ideal gas law, which states that (PV = nRT). Rearranging gives us (P = \frac{nRT}{V}). Assuming the concentration represents a mole fraction, we would need to set the total pressure and then calculate the partial pressure of CO2 accordingly. Without specific volume or total pressure values, we cannot provide a precise pressure value, but typically, CO2 concentrations in such scenarios might correspond to partial pressures in the range of a few kPa.
