A 1.000-g sample of an unknown gas at 0°C gives the following data: P ( atm) V ( L ) 0.2500 3.1908 0.5000 1.5928 0.7500 1.0601 1.0000 0.7930 Use these data to calculate the value of the molar mass at each of the given pressures from the ideal gas law (we will call this the “apparent molar mass” at this pressure). Plot the apparent molar masses against pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?

A 1.000-g sample of an unknown gas at 0°C gives the following data:
P(atm)
V (L)
0.2500
3.1908
0.5000
1.5928
0.7500
1.0601

0.7930
Use these data to calculate the value of the molar mass at each of the given pressures from the ideal gas law (we will call this the “apparent molar mass” at this pressure). Plot the apparent molar masses against pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?
Study of body parts and their functions. In this combined field of study, anatomy refers to studying the body structure of organisms, whereas physiology refers to their function.
