Use the value of the slope to determine the number of moles (n) of air in the syringe. (slope = nRT)

a) The volume of the syringe provides information about the gas volume.
b) Applying the ideal gas law (PV = nRT), the slope represents the product of the number of moles (n) and the gas constant (R).
c) Determining the number of moles is essential for calculating the pressure of the gas.
d) The mass of air in the syringe can be calculated using the slope of the graph representing nRT.
