- Plot the data given in Table 5.3 for oxygen at 0C to obtain an accurate molar mass for O2. To do this, calculate a 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). On a graph show the apparent molar mass versus the 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?arrow_forward51 What volume of oxygen at 24 C and 0.88 atm is needed to completely react via combustion with 45 g of methane gas?arrow_forwardWhy are sharp knives more effective than dull knives (Hint: think about the definition of pressure)?arrow_forward
