Question

given the mass of a popcorn kernel. told the % water in kernel, given temperature of water vapor and pressure. find hoe many mL of water vapor is there...i know you use PV=nRT but i cant find out what an example of this problem would look like

Answer 1

I would expect that you had mass of popcorn and % water, that will give you the mass of water when it pops.And if the temperature is up around 100 C, which I assume it will be to pop, then all of it will be in the vapor phase and you don't need PV = nRT
