Assume that the moles of water used in the Ideal Gas Law equation is equal to the moles of water in each kernel. Each lab group should use 25 popcorn kernels to calculate the average mass of one kernel. They then compare the mass of the flask/beaker, oil, and popcorn before and after popping to find the total mass of water lost during popping.

the pressure of an ideal gas is a constant. PV = C (1) The ideal gas law PV = nRT (2) states that this constant (nRT)is proportional to the amount of ideal gas in the sam-ple (the number of moles, n) and the absolute temperature, T. The constant R in this equation is the universal gas constant which has a value of R = 8.31J/(mole.K) in SI units.
